    Solar Thermal Cylinder Installation

    I had a solar thermal cylinder installed last week. The installers had an issue with one of the valves and installed a 15mm pipe (see red arrow in picture) instead of the 22mm at the valve. Is this going to be an issue? The 15mm then feeds into the larger 22mm. However, my concern is that...

    Unvented cylinder constantly sounds ‘on’

    Hi, I have an unvented cylinder and lately even without the boiler central heating or hot water ‘on’, the system sounds like it’s constantly ‘on’. All through the night, it used to be silent except when running, but now it can sound like it’s ‘on’ constantly for days at a time. Surely this...

    Should the pipe from the top of the Water Cylinder be hot rather than warm

    Hi all, I have a Megaflo Heatrae Sadia running from a conventionla boiler. The boiler is 12 months old, the cylinder about 6 years old. The cylinder has two separate pipes in at the bottom left, both of which are too hot to hold for more than a second. There is a stone cold pipe going in the...

    Has anyone fitted a hybrid ASHP/solar thermal/unvented cylinder system with gas boiler back up?

    Good Afternoon All, This is my first time on the renewables forum so please forgive my ignorance. I've been interested in ASHPs for about 15 years but have always doubted their economic viability - especially for retrofits. Now that there will be no gas connected to new builds in 4 years I am...
