Bought a 1960's Bungalow back in 2002 ...which came equipped (fitted by BG back in 1995) as follows :
One pipe system (3/4" & 22mm) comprising of :
Ideal 60N e type free standing gas boiler in Garage
10 radiators , all fitted with Danfoss TRVs
SMC 24 hour Timer/ clock /controller
SMC Commodore 3 port controller ( I even have a brand new spare one of these in the box , ready to replace when it goes)
Grundfos 2 port pump
Hot water cylinder in airing cupboard
Cold water tank & F&E tank(vented) in loft
3 no. Brass air vent caps in loft
The system works fine ...and appears to have been thought out quite well .......even the last radiator on the circuit is sited in the Kitchen which is also on the warmest , south facing elevation , so isn't an issue when the rad is last to warm up.
Over the years I've been lucky enough to have two really good old school plumbers to call upon ......they both gave the same advice "If you can , try and keep the Boiler you have ..... it's the Rolls Royce of Boilers"
* Unfortunately they have both now retired
On the odd occasion that servicing work was required ...such as re-siting a radiator, or preventative flushing of the system or changing a stuck valve .....here are the only issues they encountered and I wondered if you guys could offer any solutions :
Danfoss TRVs .....every start up after summer, I have to remove the TRV heads and tease /oil the pin back out ......
Would really like a solution instead of having to do it every year.
Every time the system is drained , it takes an age to purge the air from the main 22mm
flow/return pipe .The only proven solution has been to purge the air via the three air vent caps situated at the highest point of the system ..in the loft .....and then it takes an age as only a small amount of air is released, whereupon you have to circulate the system ...then purge some more air ...and so on . The last occasion took 4 hours to get the air out !
Would an air separator ? or perhaps a bottle vent work to get the air out automatically ?
