Previously I had a 40 year old boiler with hot water tank which was also sited very near the bath. Just didn't understand what I was giving up when I lost my hot water tank plus modern health and safety where people are unable to use common sense when using hot water.

Just found label attached to another document. This states: Greenstar 4000 30 kW Combi NG GR4700iW 30 C NG And then the GC number you mentioned I assume the 30 kW on this label means the correct boiler was supplied. When I opted for combi boiler I hadn't appreciate the hot water temperature...

Hot water temperature set to 60

What is the GC number please.

In November 2024 I had a Worcester Bosch Greenstar boiler installed. During discussions about my requirements when I advised that I bath rather than shower I was informed they would install the 30 kW model rather than 25 kW model. I am disappointed with the hot water temperature. There is no...

It's the 30kw model or so I was told as they were aware I bath rather than shower but there isn't a label on the outside of the boiler. Don't know what is behind the cover. This temperature shows on the hot water menu on the controller I have an old cast iron bath which also lowers the water...

I had a Worcester Bosch Greenstar 4000 installed in November 2024. I wanted to increase the hot water temperature above 60 so I can fill my bath more quickly with hot water for my occasional soak in the bath. On the boiler display the maximum hot water temperature is 60 yet on the Comfort + 2...

I have an increasing damp patch on an external bedroom wall near an old chimney. It started with the wallpaper and polystyrene sheet coming off the wall which I thought was the paste failing as I have similar bits peeling elsewhere. Then the plaster started to crumble and show damp. Years ago...

I'm confused. In the summer if the heating is off, why would the boiler circulate. I would only need hot water in the summer and perhaps some heating to warm the bathroom before a bath or shower in cooler autumn days before winter.

I am having a combi boiler installed as my 41 year old gas boiler has died. In the old system there was no thermostat, only timer control so had to guess home arrival times etc. and TRVs on all radiators apart from the one in the kitchen. It's a 3bed house with single occupant. I generally...

Thank you all your explanations and advice. Right or wrong I've decided on a combi boiler. I have other questions but I will start a new thread as they relate to the new system.

That's what my system is. I can't have heating on without hot water on. Why did you go for a system boiler. In the summer I was thinking about replacing the heating system especially as my only control is a clock and I have to guess when getting home and sit in a cold house if home too early...

Noting in the system has changed. Only noticed an issue with two lukewarm baths and a subsequent test of heating before winter when I saw water coming from the overflow pipe and went to the loft to check and found a warm cold water tank. Did a short run of central heating this morning to see if...

In 1983 a Potterton Kingfisher floor standing boiler with pilot light and central heating system was installed. It's gravity fed with hot water tank. The radiators have TRV's which don't seem very responsive to temperature changes and the only thermostat in on the boiler and for heating/water...

My flat roof has a crack in the felt. Previously I have patched the roof with a piece of felt and stuck it on with felt adhesive. To do the job I need to buy more felt adhesive but most places do not sell it in smaller quantities, only large tins for £25. As the patch is only 30 cm by 6 cm are...

It's a wooden door. I haven't tired to remove anything yet. Thought I would ask before I did anything.

This morning I closed my back door and when I ttried to reopen by pushing down on the handle it wouldn't open. Eventually I did get it to open and have sprayed it with WD40. The handle still doesn't fully retracted the latch (if that is the correct name, not sure) into the door. As a temporary...

I was guessing size. When the weather improves a bit I will check and see if I can set the ladder up safely to have a look. I don't want to take a fall and spend hours lying on the ground.

My overflow pipe if memory serves me right is metal and about 2" in diameter. What could I buy to easily attached that would comprise of elbow and down pipe. All the pipe I seen in DIY shops are plastic. How do I attach the elbow to the original. There is no thread on the pipe. The end of the...

Thanks but way beyond my DIY skills
