PIV Energy Usage

[Neoc]

Hi I have a Vent Axia Pure with Heater unit installed 2 months back . I have been tracking the energy usage and it is going upto almost £ 1.2 per day, approx 2KW usage in a day. 

 

Is this as expected as I was under the impression that the running costs are much much lower? Any way to bring the running costs down ?

 

Any feedback is appreciated

Disable the heater and it will be a penny a day.

Your electricity must be very cheap.

 

2 kW x 24 hours is 48 kWh/day.

 

£1.20 / 48 kWh is 2.5p/kWh.

 

If I could get that price my house would be at 28°C and my bath would be full of hot water twice a day.

I have the Nuaire version (with heater) I bought the heated version as I wasn't sure of the impact of cold air on house temps in the winter and thought I'd be better having it and not needing it than not having it and needing it (the difference in cost was pretty minimal)

 

I thought I had the heater disabled but that little cold snap in November caught me out - we were on holiday and the CH was on very low - pretty clear something was driving the additional consumption and it turned out to be the PIV heater

 

Normal daily electricity usage when the house is un occupied is 5.5 kWh. This jumped to 9.0 kW when we had the cold snap so the heater impact was 4.5kWh per day (or an additional £1.12 per day)

 

The PIV unit has been running all winter on speed 2 (so consumption of 5W) - that does a good job in AC terms and the air under the outlet might be a little cold you can't feel that a few feet away and it's nicely dropping the humidity in the house when running (scheduled times).

 

It (heater) is now turned off / unplugged.............
