Heating water is one of the largest line items on a hotel's electricity bill — and one of the few you can cut without touching guest experience. Ecotech designs, installs and maintains heat pump hot water systems for properties from 18 rooms up to a 700-room five-star chain.

Boilers and immersion heaters run every hour your property is open. The cost is steady, predictable, and quietly enormous — which is exactly why it never makes it onto the agenda.
A heat pump moves heat instead of creating it, so the same hot water costs a fraction of the electricity. In Thailand's climate that gap runs all year, not just in summer.
Guests forgive a lot. A cold shower at 7am is not one of those things. Undersized systems fail at peak, not on average — which is why average-load sizing keeps catching properties out.
The first question almost every owner asks. The answer is none. We build the new system alongside the old one and switch over once it is running.
A 4-star hotel on Kata Beach, Phuket replaced its electric boiler with an Ecotech heat pump system. The saving was large enough that the owner extended it to all 156 rooms.
Actual figures depend on your hot water volume and current system. We measure yours during the free survey before you commit to anything.
Every project below is our own work, photographed on site. We name locations and star ratings rather than brands, because our clients prefer it that way.
Taken from systems we have installed. The right size for you depends on your peak draw and number of outlets — our engineers calculate it free after the survey.
| Property size | System installed | Hot water storage | Reference project |
|---|---|---|---|
| 18 rooms (per building) | 1 × 300 L/hour heat pump approx. 3 kW draw | 500 litres | Kata Beach, Phuket |
| 60 rooms | 2 × 300 L/hour heat pumps | To suit usage cycle | Kata Beach, Phuket |
| 200 rooms | 2 × 1,200 L/hour heat pumps | 8,000 litres | Koh Yao Yai, Phang Nga |
| 208 rooms | 6 × 300 L/hour heat pumps | 7,500 litres | Tub Kaek Beach, Krabi |
| 700 rooms | 2 × 1,200 L/hour heat pumps per building | Parallel, per building | Patong Beach, Phuket |
Systems run in parallel, so you can start with one building and extend later — which is exactly what the Kata Beach hotel did.
Our engineers look at your existing system, outlets and available plant space. No charge, no obligation.
We compare your current running cost against the heat pump system, in writing, with the quotation. You see the numbers before deciding.
The new system is built alongside the existing one. The property stays open and guests keep their hot water.
We switch across, hand over, and stay on: 1-year parts and labour warranty, annual service, and IoT monitoring.
