From Baguio to Palawan, families, hotels and and businesses rely on Thermo Tank for sustainable hot water
The report from guests has been positive and we have not had a complaint about a lack of hot water since we finished the install.
Installing 3 solar water heaters of three different sizes, our electric bill went down from P19,000.00/month to P9,000.00/month That's a savings of P10,000.00 a month. I am sure a big bulk of the savings came from the use of solar water heaters. Solar water heater user since March 2011
Just want inform you that the solar water heater is working flawlessly. Even in the period of cloudy days it makes plenty of hot water, we are very satisfied with it. Your solar water heater is doing really great, we couldn't find a way to finish all the hot water it's producing!
Just spoke to a good friend of mine who owns a resort in Cebu, I told him how satisfied I am with the solar water heater system you guys installed and recommended your product.
Thanks for fitting me into your busy schedule and installing your solar water heater before I left the Philippines. I have some friends staying at my home now and they said it is working well.
Definitely the best investment of my house!
The 1st solar water heater we bought from you 5 or 6 years ago outlasted another brand which lasted for only 1 year or two. It also outlasted 5 USA heat pumps. Your solar is working till this day that's the reason we are changing all the heaters to your solar water heaters.
Yes, we realized big saving using the solar water heater that your company installed for the dorm. I saved and still is saving good money due to the Solar Water Heaters.
Thank you sooo much! We're very happy with your product! Typhoon tested!
It has been a little over 2 years that I had my Solar Water Heater installed by the great company SOLAR THERMO TANK. I really enjoyed taking a warm shower when the weather is getting cold and at Php 0.00 cost. The water is getting so close to boiling point that I can easily make a coffee or a nice cup of tea. If I had to do it again, I will not hesitate to contact SOLAR THERMO TANK to do the installation of the system. A reliable company. Thank you again for this wonderful system.
Everytime I take a hot shower, I am thankful for the water and the sun 🙂 Bought our solar water heater in Nov 2015. Was very happy that it was available in Baguio at that time. I’m very thankful that I can enjoy hot water anytime of the day without worrying about power bills or our safety. No maintenance costs and after 10 years, it’s good as new and it withstood the strong typhoons. I definitely recommend this product and seller - excellent quality and service and after 10 years, we have more than recovered our investment. ROI is 100%+++ not to mention we are helping the planet by using free energy from the sun.
