Hi I am new to this forum so please be easy on me. I am sure i have an issue with my boiler (please correct me if i don't). We moved into new property in Dec (purchased as repo) and previous owner removed the existing boiler from the loft. Anyway i had a brand new Vaillant Eco tec plus 831 with VRT450 Room stat.
My issue is that my gas usage seems extremely high (3 bed detached, loft insulated and i "think" cavity wall.
Now i had problems balancing my system , which i dont think is entirely correct but all radiators do heat up at the same time and upstairs is always 2degree lower than down. This temp is great but my meter is running round at a rate of Knots. I have 11 RADs mostly singles with a couple of doubles and 2x flat tall panel rads in kitchen and room (these two are the worst to balance) . I don't think my return temp is as low as it should be circa 5/7 degree differential . I did get this to 10/11 but lost after re-adjusting rads. The boiler was initially set on AUTO. I have range rated to 15kw, then 13, kw and finally 10kw, but usage is still high. I have lowered the pump to number 1 and have ordered a radiator thermometer to get the current flow. (ABV wound in to stop bypass of flow)
I have taken readings from weds 2pm to 11.30 today:
Weds @ 2pm 8919.33
Today @ 11.30 08936.689
Can someone calculate what this equates to in £amount
Over 2 minutes the last digits in red were : (this was on Auto)
.094
.145
Also when my boiler has heated up and settled should the return temP HOLD OR SLOWLY INCREASE
i AM CURRENT USING approx 6-10 units of gas per day is this right and how mush is this daily. Heating on constant 21 degree 5.30 am to 10.pm and set back to 18 night
