   - OR -   
Q: i need to get a replacement head for my radiators. its honeywell but i dont know anything else. have you got an e mail address i can send you a picture please. i can only do it on my phone.

A: Yes, you can email us sales@heatingcontrolsonline.co.uk
Q: Are the Honeywell "Traditional" and "Classic" TRV heads mechanically the same? I have a system running with "Traditional" Honeywell TRVs (VT117) and have had to replace them frequently because they stick "open". The Honeywell catalogue talks about their TRV's having been "improved" and encouraging users to replace old units with new ones of the "classic" design. But both the "Classic" and "Traditional" designs appear to work using the same principle, only differing cosmetically. Your advice would be much appreciated. Thanks.

A: The Classic (e.g. T4221GB) valves have a more responsive sensor in them, so have a slightly lower Hysteresis (0.25K vs 0.4K) and a quicker response time (20 mins vs 23 mins)
Q: Hi Can a Honeywell ( VT100E )thermostatic radiator valve be replaced without draining the system or is it just the top part that can be. Thank you

A: Only the head can be replaced without draining.
Q: Hi do you have replacement heads or adaptor S for Honeywell 9650 please Regards Tony

A: 9650 is the date of manufacture. Please email us a photo and we will recommend a replacement.
Q: I have some Honeywell TRV with code marking on side 0925B, is the above a suitable replacement. thanks Chris

A: Unfortunately 0925B is the date code rather than the model number. Please email a photo and we will identify and advise.

A ok mate, all good
Heating Controls had the best price for the Watts Vision products that I needed. Shipment was swift, I was up and running within 4 days.
Always a swift service when ordering parts. Any questions are answered quickly and delivery is very quick would recommend Heating Controls Online to any one.
