HomeBoost

A mains fed system is one which is fed directly by the mains water such as a combination boiler or an unvented hot water cylinder.

Measuring the water flow is an important step in choosing the right pump. Water flow rate is measured in litres per minute (L/min).

To measure the water flow rate, you will need a measuring jug and a timer.

1. Hold the measuring jug under the outlet which will be boosted.
2. Turn the outlet onto fully hot or cold (depending on which is to be boosted).
3. Measure the water in the jug after 10 seconds, in litres.
4. Multiply the amount of water by 6 to measure the number of litres per minute.

For example, if you gathered 600ml in 10 seconds, to calculate the flow rate in litres per minute – 600 x 6 = 3600ML per minute = 3.6L/min.

You can also use our interactive flow calculator to work out the flow rate of a single outlet.

LED Pattern	Denote
One green light steady on	Power On
Top light steady greenLower light flashing green	Pump in running mode, Faster flash, higher the pump running speed.
Both green lights alternate flashing	Sufficient mains water flow through pump without pump running
Top light steady red	Overheat (motor speed will be limited until temperature drops, or will cut off completely for safety in extreme cases)
Lower light flashing red	Internal fault. Switch power off at mains supply for 30 seconds and switch back on.

Using a HomeBoost fittings kit will ensure smooth and efficient installation. The kit includes high quality brass connectors and an isolating valve to ensure easy servicing, with the connectors designed to allow the pump to easily slide out when required.

HomeBoost uses smart technology to monitor the mains water flow rate into a property. The flow turbine inside HomeBoost recognises the incoming natural flow of water passing through the pump, a signal is sent to pump to convert this into flow rate. If HomeBoost recognises poor flow, between 3L/min and 12 L/min, it will activate the motor and increase the flow rate up to 12 L/min (the maximum flow rate allowed to be pumped directly from the mains). If the flow turbine recognises more than 12 L/min, the signal is sent to the pump to enter in idle mode.

If you do have poor incoming flow rates a HomeBoost could be used to help fill the TankBoost.
