Hi, I've been having a bit of problem with rads at end of circuit taking a while to heat up. I've recently replaced them and balanced them as best as I could. I still have the issue and began investigating the pipework I have found a small section on the flow and return that goes from...

Hi All, we have a roof that's has the horrible spray foam insulation on the slate tiles. We Also have the traditional 50mm loft insulation and recently tried to get it upped to 270mm. The loft insulators refused to lay the additional insulation siting condensation and ventilation...

Hi All, Aristion A23 Combi decided to leak its contents onto my garage floor over the weekend it looks like its coming from the flow pipe of the CH on the left and the water that was dumped was slighlty dirty so assuming central heating water. Ive attached two pics I know most people...

sorry for reposting this I moved into the house in august and the system is a ariston a27 combi, shortly after moving in noticed the bottom half of three of the radiators were cold but top half boiling hot. I also had the filling loop and a gasket replaced as water was leaking very slightly...

Hi All, Ive been trying to tackle a problem with three radiators I have downstairs that appear to have significant sludge buildup. Hot on top and cold across most of the radiator/s. I intitially got a powerflush done by a local plumber/Gas engineer but this failed to shift any sludge. We...

I have a Y plan heating system and when the hot water is heating up on its own the water is backing up via the vent pipe and depositing water into the FE tank. The speed is set a 1 on the grundfos pump. When the Rads are on their is no water being deposited in the FE tank via the vent even if...

After running ds40 through my system because of some annoying kettling now gone :) I now have an aeroplane sound from around the top of the boiler, this seems to kick in after about 10 mins of the CH firing up. If i run the pump at its lowest speed the sound is miniaml but rads take alot longer...

Hi, I have a potterton suprima 50 and have an issue with it whistling for about the first thirty seconds of use and occasionally it grinds to a complete halt and large bangs can be heard from within the beast. Speeding the pump up seemed to cause more bangs. I have recently added some...

I have a small leak on my HW circuit, it's the return pipe i think at the bottom of the cylinder there is a join where it connects up the hw cylinder to the rest of the HW circuit. My issue is wether this joint is a 22mm isolator valve or 22mm double check valve. ? The bathroom rads are on...

I have a potterton suprima 30 with the new circuit board but since firing up my rads for the winter i have a banging noise which occurs after about 30 mins of use. The banging seem's to be coming from the pipe that feeds the pump and boiler. All radiators have been checked for air and i...
