Efficiency consultants?

[Tony K]

Is there such a thing? 

 

I recently moved in to my SB, and whilst it is a joy, I am of course experiencing a raft of small teething issues related to actually living here with the family. 

 

Chief among these is the best configuration of the ASHP, mhvr, underfloor heating, water heating, and suchlike. Each constituent part has a range of possible settings, and my knowledge on each is basic. 

 

If I've learned anything from the many insightful and detailed discussions on this forum, and also from the many YouTube channels from people sharing thier experiences, it's that a reasonably detailed level of knowledge is required (more than I currently have, despite having learned the basic principles), and also that there seems to be an element of trial and error over time. 

 

Has anyone ever engaged a consultant to assess their overall domestic apparatus, and advise on the options to achieve greatest efficiency? If so, who, and did you gain much from it?

Just break things down in piece parts.

 

MVHR set at building regs for the first year. After that you can reduce a little, based on CO2 levels and humidity. But wouldn't go much lower than 0.3ACH.

 

Water heating set cylinder thermostat to say 48, set a timer window of heating for 1 hr twice per day. Assess usage.

 

Set ASHP to weather compensation run 24/7, or set flow temp to 35 and use a single thermostat (assuming no radiators).

 

That will cost you £2k, and a consultant would tell you no different.
