Does that size sound right for 19 rads? I'm calculating the rad size for each room when the gadget arrives see if that's an issue too

I have a bungalow already...I rent it out! 🤣

The cost of heating the house! My average monthly winter bill is £300+ (I don't have the heating on timed) so the idea of running the heating overnight is terrifying 😳. I literally only put the heating on when it's freezing. I use small electric heaters in the rooms that I do use... But when I do run the heating I need all rads to heat up efficiently.

Well, only to Cadent.

Local company fitted but didn't do a flush. Fell out with him big time as turned out over weeks we were being slowly gassed!!

The boiler is 2 yrs old. Only drained fown once in 20yrs. The last rad I took of was very black so just assumed a good flush would eliminate one less question mark...? One rad is very temperamental. I'm genuinely too scared to run the heating too long to rebalance due to cost.!

I have! None have bothered to respond!!

Hi Jo I did the test last winter of closing all but the 4 and pushed the heat to those and they all heated up well. Pump is at highest setting dT on each rad varied wildly! I used a multimeter on every one trying to achieve 12 degrees ish but couldn't get anywhere close on any rad

Quick recap....19 rads, sealed system, 4 rads refuse to heat up. Last year, after much effort to balance all rads unsuccessfully I eventally shut off the 4 (conveniently in one room) rads and shut the door on them! Now I want to try and bring the 4 back to life. They are all the gtound floor and furthest from the boiler, all column rads with 2 being cast iron. The remaining 15 are all hot and functioning well. Is it simply a case of turning the 4 back on TRV AND LS and with abit of noodling hope they heat up or do I have to balance the whole system from scratch?

Estimated cost to power flush of 19 rads? In Suffolk?

Looks like the rats have finally gone or at least taken a break! God it's been a nightmare and cost about 3k+..... New bathroom, sewer valve, traps, poison, Christ knows how many rat men......gaps blocked, trees pollards, grease on gutters and downpipes....the list goes on. Chickens still there but for now peace reigns!

Ah, OK. It's a huge house to scrub@ is there a spray option or paint product that has algaecide mixed in ? Appreciate your advice alot

Sorry to be brief; What is the purpose of the algaecide ? Does it prevent growth? Help paint adhere? If it wasn't used would repainting fail? Thanks

Yep, got those on the downpipes

Only one way in from the sewer and if they came in that way they would pop up in the loo!
