On this job the customer had a conventional boiler, in the kitchen, and a ‘gravity fed’ hot water cylinder on the 1st floor, of their 2 story terraced house on Forthbridge Road, just off Clapham Common,, SW11.
They wanted to update their system, and specifically wanted to increase their water pressure, as they were having a loft done in the near future and would be adding a new bathroom, along with updating their 2 existing bathrooms. Like many terraced house in the Clapham area, they had quite a large basement, so what we proposed was to move everything (except the boiler, which stayed in the kitchen), down to the basement, where it was altogether and out of the way.
The solution we installed consisted of a cold water storage tank, which was filled by the weak, existing cold water mains. Then from there we boosted the water to the rest of the house, by way of a large ‘constant pressure pump’. Before the cold water tank, we installed a water softener, to ensure softened water was pumped to all the outlets, except the kitchen and garden taps. And because it was in a basement, we fitted a Saniflo ‘Sanishower’, which will pump away any water that comes from the overflow of the cold water storage tank. For the hot water cylinder, we recommended a Worcester Bosch 210 litre unvented hot water cylinder, giving you an excellent flow rate through out the house, and ensuring if you open one tap or three, at the same time, you won’t notice a drop in water pressure. Finally in the kitchen we fitted a Worcester Bosch ‘system’ boiler, along with a wireless, programmable roomstat. We also powerflushed the entire house, cleaning out all the existing pipework and radiators. And then fitted new TRV’s (Thermostatic Radiator Valves) to all the radiator, ensuring the customer had a the most energy efficient system possible.
