Sales, Installation and Service

We Install, Service and Repair most Tank and Tankless gas Water Heaters.

The standard “Tank” Water Heaters, have a reservoir of stored hot water, typically 40 to 60 Gallons. The total volume of hot water that is available, is limited to the tank’s size. The newest tank models will last for many years and require only a minimal amount of maintenance.

The standard Tank type Water Heater is one of the least efficient appliances in your home. The Efficiency ranges from 58%-68% approximately. Note, the thermal efficiency of the tank, decreases with age. Tankless water heaters, on the other hand, are up to 99% efficient!

A properly sized Tankless Water Heater will provide continuous hot water in one of the most energy-efficient ways possible, with heating efficiency as high as 99%. This is the most efficient way of heating water while conserving energy and saving on heating costs. These machines provide a steady flow of hot water, as long as you need it & when you need it. Since there is no tank to store the heated water, there are no standby losses and no sediments as in the case of a tank.

On-demand Hot Water

Another benefit is that tankless water heaters are wall mounted and require much less space than conventional tank-type water heaters. This frees up valuable floor space in the home for other uses.

While a tankless hot water system costs more to install, it saves a lot of money on monthly utility bills over the long run. It’s a powerful solution for anyone that wants to reduce their carbon footprint and save money by eliminating the need to pay for energy required to keep the water hot 24/7.

In the winter of 2019 my tankless water heater froze and broke. Amit promptly came out to replace it with a new standard water heater. Professional, and clean workmanship. Good price, good warranty.

My hot water tank started to leak over the long weekend and when I called NASA Heating and Air conditioning the following business day, Amit was able to provide me a quote for natural gas hot water tank installation over the phone. On top of providing me the quote, he was able to schedule the hot water tank installation the same day.
