Hot water recirculating pump is installed on your hot water heater. This hot water recirculating pump sends hot water to hot taps and showers whenever hot is turned on without waiting for the hot water to reach the faucet. This hot water circulation system eliminates lukewarm water, which can be found in homes that don’t have this type of feature. Installing a hot water recirculating pump also reduces your energy bill because you use less energy when heating just enough hot water rather than re-heating all of it every time someone turns on hot tap or shower. Hot water distribution systems are especially useful for homes with multiple bathrooms or larger families. There are 2 types of pumps:
- Full Recirculating Pump System
- Recirculating Pump Comfort System
