3 Advantages to Installing a Hot Water Circulation Pump
There are several advantages to installing a hot water circulation pump. There may be some disadvantages as well, however, so take care to research the available options and make an informed decision before purchasing a new unit for a home or commercial building. Things to consider and compare against a standard hot water heater tank would be the initial purchase price, the tank size, ease of installation, repair and servicing ease and cost, and annual utility bill cost.
For example, the circulation pump may cost a little more up front, but provide greater utility savings down the road. Or, if you live in an area where these systems are not common, there may not be many professionals around qualified to repair it, so service calls may cost more.
Advantage 1 - Circulation
Depending on the layout of the house, a hot water heater may be located close to one shower or sink, but be a long distance from another. Sometimes this means that it takes a long time for hot water to travel to where it is needed. This situation can be helped with a hot water circulation pump. The pump pushes the hot water further, faster, so the wait for hot water is not as long. This system can also help the pipes throughout the house or building to stay warm, preventing them from freezing while it is cold outside.
Advantage 2 - Money Saving
Purchasing a hot water circulation pump will usually cut water and electric bill costs, and gas bills too, if your water heater system is gas. Since the pump delivers hot water faster, less water is wasted by running the tap waiting for the hot water to arrive for a shower. Since less water leaves the tank, the tank does not have to work as hard refilling and reheating, and this of course saves money and also adds life to the tank and its parts. The air heating bill may also be lower, simply due to the added heat circulating around through the water pipes. This does not produce a lot of heat, but every little bit helps to maintain average comfortable temperatures. The power source used by the circulation pump itself may add a bit to the electric or gas bill, but overall annual utility bill savings should be greater in the long run.
Advantage 3 - Connection
Another advantage to a hot water circulation pump is the connection. In addition to greater efficiency, the pump is designed to be more simple to repair or replace than a regular water tank. The valve at the top makes it easy for cold water to go through, circulate, and become hot water. Waste is eliminated, and speed is increased. Cold tap water is also run through the circulation pump as well. This is not dangerous, has no disadvantages to drinking the water from the tank, and it will save time, money and water.
