Frequently Asked Questions
How much water can the 1.0HP chill?
Up to 600 litres outdoors in the shade, or up to 750 litres indoors in an air-conditioned room. Outdoors, warm air heats the bath while the chiller works, so the same unit looks after less water. For a bigger bath, the 1.5HP handles up to 1,000 litres outdoors.
What is the difference between the 1.0HP and the 1.5HP?
The cabinet, screen, filters and features are the same. The 1.5HP has a bigger compressor, with 4,085 W of cooling against 2,500 W, so it chills more water and gets there faster. The 1.0HP is the lower-priced choice for a smaller bath.
What does T3 mean?
T3 is the climate class for hot countries. A T3 chiller is built to keep running in the heat Thailand has for most of the year, where a unit designed for a cooler climate works at its limit. Every chiller we sell is T3.
What power does it need?
It plugs into an earthed Thai three-pin socket on its own circuit, with a 16 A Type C breaker and a 30 mA RCBO. It draws about 6 A. If there is no suitable socket where the chiller will stand, a licensed electrician can add one before delivery.
Can it go outside?
Under cover, yes. It is splash-rated, but it should not sit in the rain or in direct sun. Keep 500 mm clear around it for airflow.
How cold does the water get?
Down to 0°C. Most people plunge between 3°C and 10°C.
How do I control it?
On the 5-inch touchscreen, or from your phone over Wi-Fi with the Tuya app on iOS or Android.

About this chiller

Overview

It suits baths up to 600 litres outdoors in the shade, or up to 750 litres indoors in an air-conditioned room. Outdoors, warm air heats the bath while the chiller is cooling it, and the chiller sheds its own heat less easily into hot air, so the same unit looks after less water outside than in.

For a bigger bath, or one that sits in the heat all day, the 1.5HP gives 63% more cooling in the same cabinet.

It is rated T3 for tropical climates. It heats as well as cools, keeps the water clean with filters and ozone, and you set it on the touchscreen or from your phone.

Delivery

Every chiller ships fully assembled in a timber crate. We deliver to the kerb or ground floor.

Plan for two people to move it into place. The weight is in the specifications. Once it is on a flat surface it rolls on its wheels.

If it is going upstairs, onto a roof, or through a narrow gate, a lift or a tight lane, tell us when you order so we can plan the lift.

Installation

The chiller arrives ready to run. It sits beside the bath, not inside it, and it is not plumbed into the house.

Wheels
The 1.0HP and 1.5HP ship with their four wheels packed separately. Fit them first, using the sixteen cap nuts and the tool in the box. The 2.0HP arrives with its wheels fitted.

Position
Stand it upright on a level surface beside the bath. Leave about 500 mm clear behind and to each side so the fan can move air.

Keep it out of direct afternoon sun where you can. A chiller that pulls its own hot exhaust back in works harder and holds temperature less well. It is splash-rated, but shade, cover and airflow do more for its performance and its lifespan than anything else you control.

Plumbing
Two 1/2 inch connections, an inlet and an outlet, join to the bath with the two hoses supplied. Our baths use the same 1/2 inch fitting, so nothing needs adapting. The pre-filter and its joint are in the box, and the user manual shows where they fit. Wrap threaded fittings with the waterproof tape supplied.

Water runs from the bath, through the chiller, and back.

Electrical
The chiller comes with a Thai three-pin plug. Plug it into an earthed socket on its own circuit. Do not share that circuit with lighting, a pump or a second chiller.

Supply: 220–240 V single phase, 50 Hz

Breaker: 16 A Type C MCB

Protection: 30 mA RCBO on that circuit

Cable: 2.5 mm²

Outdoors: a weatherproof socket

A Type C breaker matters. The compressor draws a surge on start-up that trips a standard Type B breaker, and a shared circuit will trip reliably.

If there is no suitable socket where the chiller will stand, have a licensed electrician install one before delivery. Electrical work is not included in the price.

Running it
Set the temperature and leave it. The chiller holds the water there. The first cool-down from tap water takes the longest: a bath at the top of the chiller's range, filled in the evening, is usually cold by the next morning.

Warranty

If an electrical item stops working within the warranty period, we’ll send you a replacement free of charge.

16 months against defects in materials and workmanship. If an electrical fault stops the chiller working inside that period, we send a replacement free of charge.

The warranty does not cover damage from incorrect installation, running the chiller without water, or skipped maintenance.

Care & Maintenance

Rinse the filter cartridges every 2 to 4 weeks, depending on use. The housing unscrews with the filter wrench supplied. A spare cartridge is in the box. Replace a cartridge when rinsing no longer brings it clean.

Check and rinse the pre-filter at the same time.

Change the bath water every 4 to 6 weeks at home, or sooner in a commercial setting or if the water turns cloudy. The ozone system cuts down on chemicals but does not replace water changes.

Keep leaves and dust off the fan grille, especially outdoors.

Never run the chiller without water flowing through it. Running it dry damages the pump.

Before storing it or moving it any distance, drain the water from the chiller and the hoses.

Wipe the panels with a damp cloth. No abrasive cleaners, and do not spray water at the screen.

Returns & Refunds

Stock items can be returned within 7 days of delivery in resalable condition. Custom and made to order items cannot be returned once production has begun. Faulty goods are repaired, replaced or refunded at our cost.

Common questions

Everything you want to know about saunas & heaters

Outdoor and indoor cabins, barrels, cylinders, cube and modern designs, plus sauna-and-shower combos — from a compact one-person unit up to fourteen-person commercial rooms. Every model is made to order and customisable to your space. Browse saunas.

Red Cedar and Finnish Thermo Pine both handle heat and humidity beautifully — cedar for its aroma and natural rot resistance, thermo pine for its stability in wet conditions. Japanese Hinoki is our premium pick. Canadian Hemlock is excellent value for indoor cabins. We’ll match the timber to your budget, look and location.

Outdoor saunas are fully weather-sealed for gardens, rooftops and pool decks. Indoor models are built for bathrooms, gyms and spare rooms. Both use the same indoor-rated electric stone heaters — the difference is the exterior cladding and weatherproofing.

It depends on the internal volume of the cabin. As a guide: 4.5kW for 3–6 m³, 6kW for 5–8 m³, 9kW for 8–11 m³, 12kW for 11–15 m³, 15kW for 13–18 m³ and 18kW for 15–20 m³. Above 20 m³ takes two heaters. Up to and including 9kW runs on single phase; above that is three phase only, which in practice means anything from a six-person cabin upwards. We confirm the exact requirement in your quote so your electrician knows precisely what to install.

Both are food-grade and corrosion-resistant. 316 adds extra protection for coastal air and chlorinated water, so it’s the safer choice near the sea or beside a pool. 304 is excellent value everywhere else. We’ll recommend the right grade for your site. See ice baths.

Ice works to get started, but it melts fast in Thailand and gets expensive. A chiller holds a precise temperature day after day with no effort — it’s the easiest way to make cold therapy a daily habit rather than an occasional event.

Our chillers run from 0°C to 42°C, so the same unit chills in the hot season and heats in the cool one. Most people plunge between 3°C and 10°C. Beginners usually start around 12–15°C and work down over a few weeks.

Our chillers include filtration and ozone sanitation that keep the water fresh for weeks between changes. We walk you through simple water care at handover — it’s far less work than a pool.

Yes. Our brochures are on the site as downloads and we can email them to you. Because every sauna is made to order, the catalogue shows configurations and starting prices rather than a fixed range. Download the brochures.

The room dimensions, whether it is indoor or outdoor, how many people, and roughly where you are. If you have a floor plan, send that. From those four things we can quote accurately.

Yes, three ways. Come to the wellness garden and showroom in Ban Suan, Chonburi, ten minutes from Central Chonburi — there is a working sauna and ice baths you can use, by appointment. We hold finished samples of all four timbers. Or we will bring the samples to you: we travel anywhere in Thailand for a fee, and that fee comes off the price of your order when you buy. Book a consultation.

Yes. RonYen Wellness Co., Ltd is VAT registered and can issue full tax invoices. Ask us for the registration document if your accounts department needs it for approval.

Yes. We deliver to Koh Samui, Koh Phangan, Koh Tao, Koh Kood and Phuket regularly. Island delivery carries a supplement over mainland freight, quoted per job, and adds a few days. Tell us the island and we will price it with the quote rather than after.

We service Thailand and Laos. We are not set up for shipping further afield at the moment.

Mainland delivery is included in the price. Islands and remote provinces carry a supplement, quoted with your order.

Yes — we deliver right across Thailand by freight. Wherever you are, we’ll get it to you. Delivery details.

See all questions

Occasionally, depending on the unit and where it is. Send us photographs of the heater, the control gear and the cabin and we will tell you honestly whether it is worth us coming or whether a local electrician can sort it for less.

Heater elements, stones, control panels and thermostats for the heaters we supply, held in Thailand. If you have another brand, tell us the model and we will say whether we can help.

Not currently.

Yes, for saunas in commercial operation. A room running twelve hours a day carries four to six times the load of a home installation, and scheduled servicing is what keeps it performing and keeps the warranty intact. Commercial servicing.

Yes — every sauna arrives in a sealed timber crate with the wall sections already built, and most assemble in a day with two or three people and the supplied instructions. No specialist tools needed. Prefer it done for you? Our team can handle the full install. Installation service.

Delivery to the spot, full assembly, levelling, fitting the heater, and a handover walkthrough so it’s ready to use the same day. It’s the easy option if you’d rather not build it yourself.

A firm, level base — a concrete pad, deck or paved area — plus a power point within reach for the heater. We send a simple prep checklist before delivery so everything’s ready when your sauna arrives.

The final hard-wire connection of the heater should be made by a licensed electrician — that part isn’t included, for safety and compliance. We supply the full heater specification and can recommend trusted local contractors.

Reserve online in a couple of minutes — pick a plan, a date and a time slot, and choose to pay online or on arrival. You’ll get a confirmation by email and text.

The Garden runs on advance bookings so every session has the space to itself — so book ahead if you can. That said, if you're passing and spot us, scan the sign at the gate or give us a call, and if there's room in the current session we'll happily wave you in.

Saunas, ice baths, a swimming pool and shaded lounge areas — everything you need for the full hot-and-cold circuit, in a quiet private garden. A towel, flip-flops, a locker and your first drink come free with every visit. Explore the garden.

It’s in Chonburi, easily reached from Bangkok and Pattaya. We’re in a private gated community — when you arrive, look for the RonYen sign at the gate and we’ll open it for you. We text a reminder before your session so we’re ready and waiting.
