Thinking of going Green??? Or do you just want to save a lot of money? Tankless water heaters supply hot water continuously at a set temperature. They offer reduced energy consumption since they only operate when hot water is needed. Tankless models save space and can be installed indoors or out.

Wether it be a basic Boiler or a state of the art Condesing Boiler, We are Factory certified on most brands to provide maintnance and repair

Temperature vs Density

Thermal expansion of water in a closed plumbing system can create a number of annoying and potentially dangerous problems. These include: the build up of unusually high pressure in a system (even when a pressure reducing valve is installed); pressure surges; and the chronic or continuous dripping of a temperature and pressure (T&P) relief valve. In addition, dripping faucets and leaking toilet tank ball cock fill valves are also symptomatic of thermal expansion.

More serious problems can also occur due to thermal expansion. When dangerous pressures are built up in a water heater, internal parts may fail such as the internal flues, fittings or water connections. If a flue way collapses it can lead to the potential release of toxic gases, such as carbon monoxide into living spaces. Thermal expansion can also lead to a ruptured or distorted hot water heating tank and may void the manufacturer’s warranty.

	Expansion Tanks - How a Diaphragm Expansion Tank Works     When water is heated in a closed system it expands. Water is not compressible, therefore, the additional water volume created has to go someplace. When an expansion tank is installed the excess water enters the pre-pressurized tank (figure 1). As the temperature and pressure reaches its maximum, the diaphragm flexes against an air cushion (air is compressible) to allow for increased water expansion (figure 2). When the system is opened again or the water cools, the water leaves the tank and returns to the system. figure 1. As the water temperature increases, the expanded water is received by the tank.   figure 2. As the water and pressure reaches its maximum, the diaphragm flexes against the air cushion (air compressible) to allow for increased water expansion.
