hot water

I have a Grant Vortex 26, and it is losing pressure. It can be at 1 bar in the evening, and be down to 0.3 bar in the morning. When the heating is on, it holds pressure, but as soon as you turn on hot water somewhere in the house the pressure drops. I thought the two systems were separate, but...

Hi All, I have a Grant Vortex Pro Combi 26 which is generally performing well but has a strange problem with a gurgling/fizzing/knocking noise when the Direct Hot Water pump is circulating. The central heating side is all nice and quiet. At first I thought the hot water was being over-heated...

Hi - I have a situation where the hot water pressure in the shower reduces significantly when I turn on a hot basin tap, but not when I turn on a cold basin tap. This is strange because there is a 28mm pipe from mains (~3bar) up to the attic where unvented is. It splits in 2 22mm pipes right...

Hello, I have read many threads relating to similar issues to mine and have checked / tried a lot of the tips, however still am having issues with the switching of the Hot Water Pump. Any help / suggestions would be very much appreciated. Overview of work carried out on system since acquiring...

I used to hear years ago that the UK and Ireland used to have 'seperate' hot and cold taps at the sink for a valid good reason , that it was by law (water laws) so that the water mains (cold) was seperate from the (hot water system) coming from the storage tank up in the loft. citing that the...

Hello everyone! I apologize if a thread like this already exists and I have missed it due to wrong wording etc. I have searched whole web and found bits and pieces but no concrete answer or other examples like mine. The background: It is an off grid tiny house where I want to install a wind...

Hi this question seems to come round and round but each with slightly different circumstances. So I have a ideal c28 mini. It has normally one light on fast blinking. That is on one second off one second back on again. The heating is fine. However the hot water when requested every now and...

Hi all hoping you guys can help and apologies if I ask any obvious questions or what's been asked before. I have an ideal conventional boiler with a Honeywell Analog stat, a hot water tank upstairs with a UP2 British gas programmer by the tank. Bought a Hive 2 and the electrician has replaced...

Settle down for a long story...... A few months ago we started getting the hot, cold, hot , cold issue with our water. we had a bit of a nightmare trying to get a plumber to have a look which is a story for another time. He recommended changing the Thermistor, so he got the part and did the...

Hello everyone, (it's my first post but I was reading posts here for a while now) The situation: My wife and I just bough a 3 bedroom semi-detached house. The house has an old back boiler in the living room behind the fire place, cold water tank in the loft and a hot water cylinder in the...

Recently moved into a house with a Worcester Greenstar high flow 440 We have hive installed Scheduled hot water mornings and evenings, are get hot water for the shower and rads. In between, when we turn the tap on full in the kitchen, or mixer shower, we don't get hot water, lukewarm at best...

Hi, I have a Valiant 824e boiler which has recently started with a problem with the hot water. After turning on the tap (or shower in my case) the hot water comes through fine, but after a minute or so the boiler flame goes out and the water drops cold. If I keep the tap running, the boiler...

Sorry for such a basic question. The cupboard with the hot water tank and the cupboard with the non-combi boiler are a mess of copper piping and I am trying to make sense of it. I want to replace a washer in a downstairs hot tap. There is a pipe that goes to the loft. This pipe has a valve in...

So I replaced my bathroom sink tap a couple of weeks ago due to my old one breaking. (The plastic square protruding part of the mixer cartridge on the old tap snapped, could not source a suitable replacement.) Got my new mono mixer tap from ScrewFix and since fitting it, I have noticed an odd...

Hey :-) I wonder if anyone can offer some advice. My combi boiler isn't providing any hot water. The pressure is fine, the thermostat up. It's on, electricity is supplied and pilot lit it's only 3 years old. The gauge on the front is saying 20 degrees but doesn't go above this. Is there any...

Morning Guys, I'm looking to install a word-burner / central heating with thermal store as our only heating system (don't have any other cost effected options). Finding it very hard going getting reliable info on such a system, just wondering if anyone has been down this road and could share...

Good morning all. We've just moved house and noticed that the HW Cylinder Thermostat was only set to 50 deg C and the hot water didn't last for long. I've raised the temp to 60 but now we are getting really loud noises coming from the airing cupboard when the heating has been on for about 1 1/2...

We just changed to a combi boiler a couple of months ago. I am finding that we have to run the hot water for up to thirty seconds before it gets hot. Sometimes it runs hot then cold then hot again. It's a brand new boiler. Is this typical of combi boilers (I have never used one before)?

hi, firstly a bit of back ground. a couple of weeks ago the hot water pipe under our both blew off (due to the chap who fitted the bathroom before we bought the house not tightening a compression fitting properly) anyway this led to the hot water pumping out under the bath for around 20 mins...

Just had the though the other day that, as hot water from combi boilers does not normally get exposed to any air and is always under pressure, is it technically safe to drink? :D Not saying it would taste nice or be a recommended thing to do though! Regards: Elliott.
