hot water

Hi, I currently have a combi system and would like to increase the water pressure for all outlets (mainly shower). I have been looking at the stuart turner mainsboost flomate mbf 12 as this states it increases mains pressure by 1.5bar...

We have gas central heating in our house for the radiators. We have a separate annexe and I want to pass the heating hot water to that building to supply a couple of radiators. If I pass a pipe between the two buildings, it will pass 1metre which is outside and above cover so needs to be...

A biasi boiler, which was working fine few daya ago. Then suddenly no ch, and giving very hot water. Temp goes upto 70c Cleaned pump, changed diverter valve rubbers, cleaned heat exchanger. Pump cleaned, is working but feels hot. After cleaning secondary HE, the hot water is not working...

Hi all As title, noticed water moving noise when on the loo and nothing was using water. Turned the stop cock off, it ceased. Started again when stop cock opened. Have checked all taps and pipes I can physically get to, no leaks. Went to the boiler (Worcester Greenstar Combi) and on...

Hi, I have an unusual question. When I switch on my hot tap, am I right in assuming that the hot water will be delivered solely to my hot tap? even though the path of the hot water may pass through multiple tee’s on the way (which will have cooled water at their other connections). I expect the...

Hi folks, I’m facing an issue and I’d appreciate your help. I have a conventional (gravity fed) central heating system with a water tank in the loft, a hot water cylinder and a diverter valve in an airing cupboard. My issue concerns my bathroom radiator and when it gets hot. It’s like this...

I have a Potterton Powermax HE 85 boiler, which is about 15 years old. This morning I noticed the boiler was off so I checked the house electrics to make sure there was no trip switch activated - there wasn't. I am insured with Baxi who are visiting next Thursday to repair and do a service...

Hi all, I moved into a new house earlier this year, so this is the first winter. The house is approx 25 years old and has the original (system) boiler with HW cylinder (serviced each year). When we first moved in we had plenty of HW. However, since winter has come along and we have had the...

Hi All Hoping for a bit of plumbing help. Our tundish is always dripping. It always (and I mean always) drips, 24/7 but since the heating has been back on its more like a flow of water as pictured. I assume its an overflow from the hot water tank but I dont understand why it would always be...

I'm experiencing a water hammer when my hot water comes on, following on from the heating. My hot water is on a timer, to come on twice a day to fill a hot water tank. If I have my heating on in between, then when the hot water come on there is a nasty, loud water hammer. The hot water /...

I have a 12-year old Worcester Bosch 37 CDi. The house has been extended (loft extension) a few years ago and it now has 7 double rads and 9 single rads all together. I've been told this is quite a lot for that boiler. We don't use much hot water because we have an electric shower and kitchen...

Hi. I have a viesmanm vitodens 50 but I've noticed it's behavior change recently I think. When running a bath for example, the boiler will fire up and start providing hot water as expected. The temp on the boiler display climbs steadily to about 85 degrees with the burner indicator showing 5...

Hello. So I’ve recently moved into a 1900’s terraced house with a loft conversion from 2001. The shower in the loft is either scorching hot or Luke warm. It also had problems with being jammed stuck until I loosened it with WD40. However, as it’s the loft, it’s not a priority (I imagine a...

Hi all, I moved in to a new house earlier this summer which I believe has a system boiler (I'm used to a regular boiler in my old house). The HW is programmed to come on twice a day. This week (as I am sure a lot of people have :)) , the CH went on for the first time. I noticed that when the...

Hi, I have a baxi duo tec 24 and its started having some weird behaviour. When I run the hot tap the pressure drops and it making a really quiet high pitch whistling sound. The sort of sound that would drive teenagers and dogs mad. No error codes and all work fine. Just want to know what checks...

Hi there I moved into a flat recently which uses a HIU for hot water and heating. I found that in the bathroom there is only luke warm water coming from the basin mixer tap and the thermostatic shower mixer. The kitchen is fine however so that tells me the HIU and water coming out is fine as...

I’m having the usual constant vs timed hot water debate with myself and just need to know how the tank behaves when supplying water. As far as I understand (and I’m probably wrong), if your DHW is timed, the boiler will come on and heat your water to 60C and go off. If you then go and have a...

Hello, We recently took down a radiator temporarily for paintwork. (We have an Ideal Logic System boiler with hot and cold water tanks in the flat, if useful to know). We re-fixed the radiator this morning but now have no hot water or central heating. We have an F1 error message - all water...

Hi everyone, wondering if I can get some advice We have purchased and moved into a one bed flat which had a combi boiler and central heating system installed in 2014. For some reason though, we have an airing cupboard in which there is a massive cold and hot water tank. We think the water...

Hi There, Wondered if anyone can help me work out how exactly my boiler works and how to use it efficiently to save money after some quite costly bills. I have a Santon Premier Plus Unvented hot water system as well as a slimline Amptec Electroheat boiler (C400) alongside. I'm pretty sure the...
