I still have a bimetal roomstat in hall with wax Danfoss TRV's on 13 of the 14 radiators in house (hall currently has lockshield).
Was considering getting a wireless roomstat to improve temperature stability in lounge but noticed the price of electronic TRV's has come down a lot.
Has anyone tried any of the budget Conrad options (or other suggestions)?:-
The EQ3 at £15.99
The Eurotronic Sparmatic Comet at £15.97
The HSA9001A at £19.99 (reduced from £49.99... too good a bargain for a Scotsman! )
Or, for around £26 a room an RF option:-
The Pegler iTemp also looks like a good option at £23 and has USB programmer, window sensor and remote programmer options for around (plus most importantly UK manuals and support).
This would cost aorund £370 for including 14 valve thermostats, a remote, one sensor for patio doors and a USB programmer but the UK support, etc seem to make this quite a good option....
Think my current TRV's are Danfoss RA.
I looked at Honeywell/ Conrad HS20 "full" systems but for 14 radiators cost is a lot higher (circa £1000) and I'm not sure I need the features of the "integrated" systems.
The main advantage of "integrated" wireless TRV systems seems to be a pump control relay- but reading other forums it seems that I'd be better replacing my "fixed speed" Grundfos pump with a Grundfos Alpha 2- less power and dynamic "load sense" means I don't need any radiators left with lockshield and no TRV, or a roomstat. (Note I on't have a combi boiler- system is boiler + boilermate 2000 heat store)
Anyone tried any of these budget options- 14 zone system for circa £250 plus £120 for a new high efficiency pump seems pretty good and may actually payback in 2 - 4 years...(unusual for my HA "investments")
