- **2011:** -10°C
- **2012:** 15°C
- **2021:** 40°C
- **2022:** 25°C

I have put 2022 to 38c

Will see how it goes thanks £2900 later !

Also down to one pump on the flow side directly into the CH and returning to HP . DHW remains as it was . A week into the modified system running and seems to be fine , there has been some frosty nights and cold airstream throughout the last two weeks, and that’s reflected with the heating on in the evening . I have brought the water law back to 38c from 40 , OK so far . Is Homely beneficial at  this time of year?

I know from my Bills that they are higher than before but only because I am in this in between stage that now the temperatures in the house are more consistant the the whole idea of bypassing the the tank and or making it a volumiser has to be completed in order that the system is optimised , but I cant get someone to do it . I am committed to completing it , and then savings will be even more , Im sure of it , I am down the a flow temp of 40c now , previously 42 for two weeks,  meanwhile the daytime temperatures are helping things a little now.

I cannot get anyone to respond to a request locally to come and have a look at converting a buffer tank to a Volumizer therefore eliminating the constant mixing in this . 

Is it the time of year or lack of committment at this time of year . Due to colder temps and time of year?

The reason being costs normally should have gone down daily given the OAT at this time of the year. So trying to get a plumber to submit his time and have a look at my system seems impossible . 

Shoud I revert to my older system in involving opening lockshields and shuttin down TRV's to suit rooms . Certainly cheaper than exposing the flaw with the present set up or try and get a company to look at the proposed set up meantime .
