hot water

Hello. Our current external Grant Vortex Combi Oil Boiler has a problem with the initial hot water supply throughout the day. In summary: - It takes about 5 minutes of running the hot tap until we get hot water. - This is the same whether the heating is on or not and regardless of time of...

Morning everyone, We are currently without hot water and are seeing an ER 69 (with the spanner icon) code on our BIASI boiler. Does anyone know if there is anything we can do (i.e. resetting the boiler) to try to get hot water without resorting to an engineer? The boiler is slightly...

First time living in a house with a combi. When I run the cold tap it triggers the combi hot water setting, I've checked the pipes and they are all connected correctly. The combi is just over a metre from the cold tap, is this just the slight pressure drop triggering as the boiler is so close to...

Hi there, I recently moved into a rented flat - it's a nice flat and good for the money, but it's also pretty old and has (from what I can assume) a pretty old boiler system. When I moved in I didn't have hot water, the landlord and landlady haven't actually lived in the flat so when they came...

I say no hot water but ...... OK start from the beginning. (Spark to trade ... I know, I know) Was working fine until 16 months ago and we noticed we wouldnt get hot water unless the pre heat was on. If that was on, we would get hot water as normal. This became slowly less reliable until a few...

Hey all, I have a betacom 28 boiler and I’m not sure how to pressurise it again. Currently the boiler’s on 0.9BAR (it has dropped but it’s been gradual) I’ve noticed after bleeding the radiators recently I’m hoping it solves the issue I’ve got with the hot water. The heating still works, the...

I'm putting in a completely new central heating system to feed radiators (150m2 of house across two floors - about 13 radiators) and provide hot water (1 shower, 4 sinks). For this, I'll be installing a Samsung 12kw Heat Pump and a 20tube solar thermal array (58mm hot tubes with alcohol fill)...

Hi, My flat has an old pumped central heating and gravity hot water system controlled by a Danfoss 103 electric-mechanical timeswitch. [Correction from ianmcd, below: It is not gravity HW. It is an open vent system with pumped HW]. No room thermostat. Hot water and heating cannot be switched...

We have just got a top end boiler, and are ready to ditch the electric shower. As such I now need to put in a hot water supply to the shower which is currently only cold only. We have no problems with water pressure which is pretty epic since we got rid of the water bottle. here is a (cough)...

Hi, The house I am buying is a 2 bed mid terrace, and is not on the gas network. The gas combi-boiler is run off LPG cylinders, and provides both hot water and heating. This is a direct system, and there is no storage tank. I am planning to go solar at some point in the future, and I want to...

Hi all A new member here! I have bought a 3rd generation nest that I want to integrate with my Worcester greenstar 30dci classic boiler. The central heating control is straight forward enough but I can't find much advice on the hot water function wiring on my particular configuration. The...

Have searched the site for solution and couldn't find one for my problem, hopefully someone is able to advise on where I have went wrong. Formerly had potterton EP2002 controller connected to my BAXI system boiler 60/100. (See photo) This also had a thermostat wired in and has a hot water...

I hope someone can help, We have a Mitsubishi ground source heat pump system with a water cylinder with a Mitsubishi PAC-IF013B-E Unit on the front. Downstairs we have a wireless Danfoss TP500Si thermostat which talks to the Danfoss RX1 single channel receiver also attached to the unit. There is...

Hello, I have a Baxi combi boiler and I'm having problems with the hot water. When the heating is on I have no problem and can get hot water but at other times it is very hit and miss. As well when I am running the tap at a low flow I can get hot water. I have been told that this is probably...

Hi. Over the past couple of months the hot water system in my house has started making an incredibly loud reverberation when a hot water tap is opened. I would liken it to the sound of a ruler being twanged on a desk. It is very loud and fades to silence over a period of about 3 or 4 seconds...

I have a Combi boiler. I'm wondering: what's the lowest temperature that I can set the supply to taps at please? I don't have mixer taps in the house and really don't want 60C hot water coming out of the taps.

Hi, I hope you can provide some advice on an issue I'm having with my Vaillant Ecomax 835e. When I turn on DHW downstairs, the boiler fires and provides hot water as expected. But upstairs when the shower or bathtub are used, the water will get (very) hot, then steadly decrease in temperature...

Hot water coming out of the hot water storage cylinder into upstairs radiators after heating/HW turns off and running out of hot water in the mornings. I have a Glow Worm 24HX Condensing boiler on the ground floor with a pump in the same cupboard, a hot water storage cylinder in the airing...
