dhw

Hi I am seeking some advise regarding my Ferroli F24 Boiler. We are experiencing problems where when the boiler has been used for a period i.e. kids having baths and washing hair with shower it comes to the point where the mrs gets to have a bath but during this the DHW supply starts to go...

Hi, Hoping to get some help with oldish boiler - Worcester 24i RSF. Over the last few years the pressure on the DHW has dropped by about half (still just about useable for shower) and also the water temperature is very high due to this slower flow (no adjustable temp control on these, set by...

Has anyone used brick acid to de scale one [its a baxi 105e] and if so how did you go about it and did you dilute it, atb, buster.

Hi, The DHW was intermittently working and only then the white lever would disengage the microswitch. Thinking myself "clever" I fitted a service kit and you can imagine my surprise to find after a short time the same thing was happening. Would adjusting the flow rate help me out here? I would...

Hi all, one of my neighbours was chatting the other day, complaining that his DHW was pathetic. Of course I volunteered to have a look. And it is pathetic!. It's dribbling out! Hot but dribbling!. Is there a filter in these things? Looked at his manual but it doesn't say either way. He did say...

Hi to all, my first post. Sorry that this post will probably appear as one huge paragraph but for some reason or other my keyboard return key won't do anything on this forum :-( Anyway, I'm about to purchase said heat pump and having studied the wiring diagrams am getting my brain in a knot...

Probably a daft question but I will ask anyway ...... Just looking at the Ideal logic combi installation manual. It has litres per minute at 35 degree rise And DHW specific rate. What does this mean? maximum flow through the boiler? Maximum DHW Input : 24 30 35 Nett CV kW...

Hi! I have a Ravenheat CSI/HE range combi. Recently it started running cold water after a few minutes, and then back to warm for a bit, then cold again etc. Even more recently it sometimes won't even start running warm at all. The heating has been off for months (summer) but I tried turning...

Hi guys Went to a job today in a small set of offices and i was told that the hot water kept going on and off (hot then cold). What would you recommend i check? Pressure was low but I topped it up, made no difference. Is a dodgy thermostat or heat exchanger likely? What tests do i need to...

I have an indirect copper vented DHW tank heated by S plan oil boiler. CH working well. Feed from boiler to indirect hot as is the return. Tank is not heating. Cold water coming from hot taps. Soft water area. Any ideas? Ta.

Since I installed this boiler I thought I knew all it's quirks and but this one has me stumped. The DHW is working fine, endless hot water. Central heating fires up, radiators get warm boiler reaches 50 degrees and shuts down as if it's reached the correct operating temperature, pump...

the info is from cust dhw works fine when ch is in use but patchy when dhw only I tried to check the dhw thermistor but access was difficult so I popped it out and tested it in my hand and it seemed good (could be red herring) checked hex that's fine bp fine min and max. When its dhw only the...

Hi I have Baxi 105e boiler, as soon as i turn the boiler on it fires up and the DHW led lights and the boiler fires up even though the taps have not been turned on, it stays on and eventually heats the radiators up, This started happening shortly after i have had the 2 way valve changed as the...

Went to look at a 24 CDI today for poor hot water pressure. According to the customer the problem has happened overnight, the pressure on the cold main is fine and the customer assures me it hasn't changed but the hot is terrible. United utilities have been working in the area so I removed the...

I have a BAXI Duo-tec Combi 33 HE (installed June 2008) which has started to make some very loud banging noises (kettling I think & so loud the next door neighbour can hear it) when you run the shower or any of the hot water taps for a period of time. We have had this problem previously but it...

Hi, i was wondering if anyone regularly fits electric only units and what sort of performance you get out of them, look after lots of properties with storage heaters and would love to start tossing them over the balconies to install wet systems in their place thanks Dave

Hi guys, hope someone here can help a bit. I've got a procombi 120he. had it about 4yrs. Every 3 or 4 months I get this problem that the hot water cycles on and off. So I'll be running a hot tap, the boiler fires up, runs finen for 20-30secs then clicks off. No red light, or lock out. then a...
