hot water

My boiler is 11 years old (the system was power flushed then). Just recently the hot water started to cut out. I contacted Vaillant who offered a £300 fixed repair contract. I have had two visits. On the second visit the diverter valve and plate heat exchanger were replaced. The first visit the...

Hi, I have moved into a new build and have a strange problem that the builders have tried to fix for weeks, hope someone can offer a solution! The system is a Vokera Mynute boiler with pressurised hot water tank and 2 heating zones. The hot water tank also has a solar thermal coil installed...

Hi all Re-plumbing a 4 bed, 3 bath house as part of a renovation and I am trying to figure out of a Secondary Return loop is worth the extra work? The longest pipe run from the tank to outlet would be about 18m. If we made up a secondary return loop the total pipe length would be approximately...

Hello, I have a Combi Boiler (Vaillant Ecotec Plus 428) and an Unvented Cylinder (Vaillant uniSTOR VIH GB 180s). Since yesterday we have no more hot water in the house, it comes out cold or luke warm. But the heating works fine. When a hot water tap is fully opened, the boiler reads S.30 (no...

So begins my sad saga. Like most of us, I like a problem and the satisfaction of solving it and felt capable of doing so as I have had some plumbing experience (Pre Corgi) and have, in fact fitted a complete system around 20 yrs ago (Tho my mate, Bill the Plumber did the final checks) Here...

Good afternoon everyone, In a bit of a pickle at the moment and it's a bit of a long winded explanation so please bear with me. Recently purchased a new home and everything was working hunky dory for about a week. I decided to do some decorating and installing plug sockets so needed to work...

Hi All, I'm replacing an old dishwasher that came with the house - it looks like something from the 80s! It's a Cannon Hot Fill 8s. This means that there is a readily available hot water 3/4 BSP inlet hose (and drain). Looking online I can see that there is very little choice for a new hot...

I have Drayton 2 channel programmer, for a while the clock would come on for the hot water but the boiler would not start up. Discovered if we switched the heating on and then off on the timer the boiler would start up and heat the water and go off with the timer. Since the temperature has...

Hi all, I'm at my wits end after a week of boiler woes. Last Sunday we noticed a smell of gas coming from the boiler when the heating came on. We immediately called the Gas Emergency Services and someone came very quickly and detected that there was indeed a leak from the boiler. He shut the...

Hello all. We moved into a new house only a few months ago. We have an oil fired boiler and a hot water cylinder. Now when we call for hot water, the heating comes on -and when we call for heating, nothing happens. I've had a look at the mid position valve - it's an ACL Lifestyle model. When I...

Hello all, I would a very quick bit of advice. I am planning to purchase A Nest thermostat this weekend but I want to understand how I can wire it first with my setup. Please in advance forgive me if I say anything slightly stupid but I have a good understanding of electric circuits so I should...
