Hot Water Heating

Abacus will be able to serve all your hot water heating needs. We offer conventional water heaters and boiler sidearm water heaters depending on your application. The conventional water heaters won’t last as long but are less up front. We offer many types of conventional water heater. We would be happy to send a comfort specialist to help determine the best plan for your home.

A boiler sidearm potable water heater is a tank with a coil in it for the boiler to serve. It is always better to have as few burning appliances as possible to save energy. By adding the proper control to the system, we can increase efficiency greatly. We can also have the boiler stop making domestic hot water when you put the system in unoccupied if you’re leaving town for a while.

The sidearm water heaters come with a lifetime warranty on the tank. If maintained properly, the tanks will last a lifetime. The only moving parts are the pump and aquastat. Between the efficiency gain and the warranty, a sidearm is the perfect fit depending on your application.
