hot water

Any experienced plumbers out there kind enough to take a look at my hot water system drawing? You can be critical - I'm learning! It’s designed to supply PV solar preheated water to an electric water heater and then on to small bathroom (daily light use). At the end of an ‘average' day, I...

We have an evohome system, that controls both hot water and heating Heating is linked to two zone valves, and the full 12 allowed zones Switch heating to off, and hot water to off too Check smart meter at the end of the day and see 70p+ has been used on Gas (not standing charge, just usage -...

May parents have a Honeywell ST9400C, when they want to heat up the emersion heater they have to switch the HW & CH on to get hot water. With the CH on as the same time the house gets very hot, just to have a shower! CAn any one advise what can be wrong?

Hi everyone Would love some advice! We have a hot water cylinder which lost 14 degrees (48 to 34) in four hours, with no demand/usage. So I think the heat is escaping. The circulation pump (which you can see in the photo) is off, so could passive convection be the reason? The pump is always...

Hi everyone. I'm in the process of deciding if to switch from a traditional boiler to combi. One thing that is irrationally worrying me is if kids leave hot water taps running. Would that mean the boiler (if it was 30kwh boiler) would be running full pelt and using 30kwh gas every hour? Want...

Ok guys so my Range Tribune He immersion heater stopped giving hot water a couple days ago (I’m a joiner with a limited knowledge in plumbing) also the hot water capacity was never that much it would do 2 showers a day. Any ideas of what’s up with it?

Hi Guys, Had a question about a S plan system. When customer turns on a hot water tap the boiler gets demand for heating as well and radiators heat up, the heating radiator sign (Vaillant Boiler) flashes on the boiler display screen. Customer has said it has been like this for a year. I have...

Currently have 14Mx15mm run from combi to tap dhw. If I replaced the last 6M section with 22mm pipe would this help? Taps closer to boiler have no problems firing the boiler.

Hi, I need to disconnect the hot water to the kitchen tap to repair a leak but there is nothing under the sink. We have a tank upstairs: Also, I followed this video but after loosening the screw with an Allen key, the handle will still not come off. I managed to stop the cold water. Any advice...

Hey all! 👋 I need to buy one of those yellow tempering valve caps with the triangle inset on top of the lid, so I can adjust the tempering valve on my Saxon 140L hot water service.. it’s only got a crappy blue lid with no triangle inset, and I can’t adjust the valve any other way (difficult...

Hi All, I have this silly question. Water pressure for hot water is a bit low while cold water has a decent pressure. Why do they put 22mm copper pipes for hot water? It seems detrimental for already low pressure. Best regards

There was an AEG Prosource Hot Water tap (model GYB00418DT) in the kitchen when we bought our house. The 'standard' mixer handle (i.e. not the boiling water handle) has started to leak intermittently - it doesn't switch off and the tap leaks as a result. I can't find a spare tap online...

The hot & cold pipes to my bath are 15mm, shouldn't they be 21mm. The hot water is feed from a hot water tank and is a dribble whilst the cold is very strong. Should I have the pipes changed to 21mm or would an electric pump on the hot water feed suffice? If fitting a pump, are they robust and...

When I turn on water only on the logic 24 boiler the water heats up and so does the radiators. It’s a a single floor apartment with the boiler recently serviced and the safety valve and 12 litre vessel change. Using the hive heating system.

What are the factors that determine the life of a water tank? Obviously the quality of the water and the materials used to construct the tank are important. But beyond that I'm fuzzy. Is it just the number of gallons of water that pass through it? The number of "fresh" gallons of water that...

Hi all, Just looking for some advice if anyone has worked on a boilermate 2000 try to condense the story, Lived in our home 3 years with the system working fine, but 2 days ago hot water stopped. From research it now looks like the past owner already had a problem. They have changed the...

When I turn on my hot water taps anywhere in the house, after about half a minute there is a humming noise all around the house. When I turn on the cold tap, the noise stops. Any ideas what is causing this humming noise?? Thanks Michael.
