By the way, I have the spec as 1000mm high, 600mm wide. No idea of the depth. Is this the same machine you were referring to? Product code is MB240200.

Thanks for the advice. I've just rung Grunfos who've explained in great detail the benefits of their integrated tank and pump which I'm going to purchase shortly. Is this something you have installed before and can I have your work number to contact you for a quote?

Many of the freeholders who own flats in the building live abroad and don't want to spend money on a problem which doesn't affect them. I own the only flat on the top floor and therefore am singled out. Given the circumstances, I may have to compromise on efficiency. Will the Grufoss Home...

The cold water supply to my flat is very poor - about 0.5 bars. I have spoken to Thames Water who say they are required by law to supply good pressure to the 3rd floor only. But I'm on the 6th floor of a large Victorian building. They say that I may install a pump straight off the cold water...

Now that you've pointed out how to do it, it seems so simple. Thanks

I've re-edited the question and illustration as the originals were incorrect. Any ideas how to solve the problem?

I want to connect a light switch to two ceiling lights. The power supply is in a ceiling rose 3 meters away from the wall switch. I don't know how to insert illustration that I've drawn in this post but you can see it by clicking on...

My very old Valiant combi boiler needs to be replaced. Nat Grid capped off the supply after I smelt gas and the plumber who came later couldn't get the rusted pump off. It appears to be truly welded to the pipe work inside the boiler. Anyway, it's a very old gas guzzling open flame pilot...

The lights in my flat have been tripping out repeatedly over the last week. I have 12 volt halogen lights dotted throughout the property I've isolated the problem to two control panels with tripple switches - one for the hall way (two bulbs), one for the kitchen (5 bulbs) and one for the...

I need an immersion timer with a booster button that can be controlled. For example, I would like to set the booster to come on for just 15 to 20 minutes and then to switch itself off. Does anyone know of a digital immersion time with this specification?

I have managed to dig up some information about the floor mats from I can get very little heat. They are 1600 watt and 1.5m2, but I don't yet know who makes them. I wonder if the Timeguard thermostats that were installed by the developers are unsuitable for the mats. If they are, can...

I've now replaced the who element with a new thermostat and the system now seems to be working. I guess I'll never really know what the cause of the problem was but thank you everyone who offered advise.

In my new flat which was developed before I purchased, I have discovered so many problems including lcd thermostats for underfloor heating which are beyond my comprehension The make of the thermostat is Timegard (tpt44). I haven't got a clue how to work them. I've read the instructions which...

The plumber told me that the thermostat was with auto cut-out. But I don't understand why it failed to stop the water overheating. The wires were definitely connected. I triple checked them. What I did notice when removing the thermostat was that the side of the plastic head had melted. When...

I didn't check the temperature with a thermometer but with my hands. The water was scolding. This morning, I unwired the immersion thermostat which had clearly melted from the heat and was no longer functioning. I took it to the plumbing shop where I bought it. After examining it, they...

Having posted the below message and received answers that there might be a bad connection, I checked the wiring but couldn't see anything wrong. Nonetheless, I removed the thermostat and wired back in. Unfortunately, after just half an hour of the heating being on, the water is still...

Thank you for your replies. I will check the wiring first thing in the morning.

A bought a property recently with an immersion heater. The water was scolding. I tried to vary the thermostatic setting, but the temperature was always too hot to touch. I visited the local plumbing shop who recommended that I change the thermostat. After changing the device, the temperature...
