hot water

Hello all I'm returning to DIYNOT after a long hiatus and lapsed account. As ever, I only come on here if I want to know something or (as in this case) to reaffirm a decision I am about to make. I'm in the process of buying a one bedroom first floor flat, built c.1990. It's on E7 supply...

I have just bought a house with a Vaillant ecoTec 637. The previous owner had some terrible Honeywell system installed but took all the controllers. So I can’t control the system, and in particular I can’t get the hot water on, no matter what I do. I had previously used a tado system, so I have...

Hi, I have an issue with the hot water supply to our new bathroom which has stumped a couple of plumbers and a builder, short of spending a lot of money for something that might cause more problems. I'll try to explain it clearly and would be grateful for any ideas: We live in a 200 yr old...

Having moved into a house with a Rayburn it's an ongoing battle. Latest is that I thought simply switching from "Heating/Hot Water" to "Hot Water" I would continue to have hot water (heated up at the previous central heating times). Not so much. - I have a separate wireless Honeywell thermostat...

Hi, Summary: I am looking to buy a replacement battery. Does anyone know where or how to find one? I believe this is the problem. I changed the tank to a thermal store. I left the Horstmann switched off at the mains ie no power to charge the battery, for several years. Apparently they won't...

I hope someone can help with a perplexing problem I'm having with my hot water system. I have a Worcester outdoor oil boiler. My hot water schedule is set for 6am to 10am and 5pm to 10pm. The boiler will always come on at 6am and at 5pm, but it is not able to keep the water up to temperature...

Hi Can someone please offer advice on which water pump to pick? It'll be for the hotwater to the bath and a downstairs shower room, the cold is on mains and the upstairs shower is electric. We have a hot water cylinder at ground level (about 5m away from the original wall of the house) which...

Hi, first post. Engineer is booked for 5th of June. But just would like some clues. I’ve read the other posts and the zone valve is likely culprit still. ch fine Zone valve for hw doesn’t move I do hear a click in the nest heat sync when I choose hot water. If I open and lock the zone...

We’ve heard a loud noise from the pipe work above the living room recently like a tapping when the hot water comes on. Sound file https://sndup.net/7z8c Is this normal?

Greetings all. I'm after a bit of advice as we have an issue with our HW kettling and on closer inspection the wiring on our 2-port Valves looks a little suspect to my untrained eye. Background: The house was built in 2001 and has an 'S' CH/HW System installed. If the HW is on and the CH is...

Hey all, this may sound like an unusual question - I asked here about my particular setup before and people here helped me understand it, so now I have a concrete (DIY) plan here and need a sanity check. I have a Danfoss TP9000 thermostat for both my hot water and heating. However, the heating...

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)...
