Its a couple of years since I fitted alarms but on my own system on the windows I used Viper GLX vibration detectors. These allow you to set the onboard red led to flash continually on and off so as to be a very good visual deterant especially after dark. I have them on my lounge...

When I turn on a hot tap the water flows but as the flow warms up it gets slower, so I have to open the tap wider to maintain a fast flow. What causes this ? The water temp. is fine.

As regards to the movement detectors even dueltech units are not immune to false alarms from insects moving over them, I use a twin beam infra red beam unit across the garage, contacts on the door and viper on the window with the led flashing to warn a would be intruder. My car stays on the...

I have always been given to understand that at least one radiator in a system should not have a tvr fitted so as to avoid the pump and boiler running when all radiators were closed off. However I was on a site of a tvr maker and they stated that all radiators could and should have them...

What is the ideal return water temperature required to get the best out of a condensing boiler. Some say around 50 degrees on my boiler that means a temp. setting of 60 degrees outgoing, Baxi say return should be min. of 13 degrees less than outgoing and to run unit at 80 degrees. Some...

No he left that at 70 as it was, now as regards this setting some time ago I spoke to Baxi technical to ask about the best setting for this control to obtain max efficiency and was informed that flat out at 80 would be the best. They also said that the return temp. at the boiler should be a...

I have a two and a half year old Baxi du o tec 28 boiler. A few weeks ago a Baxi Heateam engineer came to replace the the spark electrode with a modified unit, he also replaced the spark generator. He made several tests and checks on the boiler with some form of meter and was on site...

Thank you for your help, I am happy to say the penny dropped this morning and the ceiling is now complete except for the part tiles that require cutting for the edges.

I am trying to fit the above in a Victorian style upvc conservatory. The area is just under 10m2 ie 3.435m x 2.840m. The shorter figure is the wall that has the front corners cut off if you know what I mean ie the victorian bit. I have obtained all the bits to build and hang the grid plus the...

I have not adjusted my own a gas safe engineer did the adjustments, I have the heat team coming to look at it so I expect they will replace it with the new type. Thank you both for your info.

Has anyone had problems with the spark gap closing. This has happened twice now, in November the boiler stopped firing up and displayed error 133 the problem was weak spark due to too small a gap it was approx 1mm. It was reset to the correct 4mm all was ok until yesterday then the same...

It is Polycarb, what are the tinted sheets you refer to.

I wish to reduce daylight not just heat through my upvc constructed conservatory. It has the usual plastic type sections, blinds would cost too much at over £2k. Is there anything I could apply to the inside.
