OK thanks Blup

Hi Foxhole, too late ordered now. We'll see ha ha. I'll let you know

Should reach the extra 1.5m each end

Hi Foxhole, 45 deg is great that's 5 deg more than my cheepie. I'll go ahead and order the Karcher. thanks

Hi, worry not thanks. I've been in touch with Karcher and they are going to let me know on Monday or Tuesday

Hi, I'll explain more. I originally bought rotating ones and they didn't work. I then bought a cheepie oscillating sprinkler (£6) to try it out before buying a more expensive Karcher one. The cheepie just doesn't quite reach the extreme of my lawn by about 1.5m each end despite having a very...

Hi, can anyone identify the model of my Westherm TRV please. Attached is a photo Thanks Regards Costeta

Hi Bri160356 I've just discovered Honeywell HR20 programmable TRVs. Not wireless but allows for individual scheduling of TRVs. Only £34 on Amazon. Much better payback period.

Bri160356, you like me work from home and probably heat the whole house most of the day. May I ask you to do a calculation on your circumstances if you could heat only your study to show I am not having a laugh by saving £120 a year and getting a 3.3 year payback on a £420 outlay. Thanks

Bri160356, response from Jasmin at Megaman, "Hi Terry, I have called Lightwave rf (jsjs designs) , who have advised we are unable to comment on exactly how this system will operate as it is very much in planning and testing stages. The main idea is When a TRV valve opens it can call the...

Bri160356 You hit the nail on the head about the LightwaveRF TRVs. New technology is not always reliable. The kit for my house would be circa £400 and a pay back of 3.3 years. The kit comes with a 2 year warranty. The kit could go wrong in year 3 and extend the pay back period. So this is the...

Jasmin, you are working late tonight. Thanks for your reply. I look forward to your investigations tomorrow. My fellow member on the DIYNOT forum is interested and the word is spreading. Thank you Regards Terry

A response from Megaman. "Good evening Costeta, I havnt seen the prototype or manuals for the new system that will be launched in 2015, so please forgive my lack of knowledge at this stage. The initial idea is two incoperate the whole system as one. Ie the home thermostat and boiler...

Bri160356, Look up Heatgenius.co.uk. They also do a wireless TRV system that uses a boiler control. A little more expensive than LightwaveRF kit but gets good reviews.

Hi, the functionality of a communications link between the TRVs and the boiler via a LightwaveRF link and boiler switch are due next year some time. However it's a good question and I've passed it onto MegamanUK.com who are answering all my questions and I'll get back to you when I get an...

But if you have both then set the house thermostat higher than needed and rely on the TRVs to control the heat output from the radiators not the house thermostat controlling the boiler. I agree they conflict.
