Fortic or other close coupled Tanks are very common in flats and other homes which do not have access to a loft. Many plumbers will advise you cannot boost the hot water from a Fortic Tank with a traditional shower pump. The ShowerPowerBooster is perfect for boosting a Fortic or close coupled tank.

Fortic Tank – Boosting Hot and Cold
Traditional pumps will try to pull out water too fast from your tank which causes the pump to cavitate and burn out and your limited cold water storage will soon run out. The Shower Power Booster is designed not to overheat, or cavitate, and it will not pull out water at a rate which exceeds the water required for a shower. It will significantly improve the flow to a bath.
You only need 5 to 6 litres of hot water for a good shower and 3 metres head which is achieved by mixing 2/3rds hot with 1/3rd cold. Changing your cold to the shower to mains pressure and just taking hot from the tank with your tank refilling at 4 litres a minute means the cold tank stays full. With boosted gravity hot and cold the tank will drain a little bit quicker but it is often ok.
It’s an easy DIY job, you can fit the pump inline using your existing pipework, and it’s a 10-minute job for most.
For gravity hot and mains cold, the fully automatic SP21S is the model that best suits your needs as it will give you the equivalent of mains pressure hot when feeding your shower (switch the cold feed to your shower to mains pressure if you have not so done already).
OTHER OPTIONS TO DOUBLE BOOSTING THE HOT
If you want to avoid changing the cold to mains pressure and double boosting the hot then fitting a SP22S to single boost hot and cold is an option. Just boosting the hot with a single boost SP2B may need a second pump added later but for some homes that is all you need.
ShowerPower Boosters can be close to your hot water cylinder or close to the shower or tap you want to boost.
