EV, Heat Pump & Solar

CharlieCroker

With all the options from different providers, I am finding impossible to  understand my options.

I have two Pure Electric cars, 12KW Solar Panels, Battery Storage and a Air to Water Heat Pump.

Does anyone have a recommendation where I can benefit from goods rates for Charging, also the option to add  a set rate for the Heat Pump and a decent feed in rate per KW.

I can find rates with add ons for the EV charging, but not that also allow a discounted rate for the Heat Pump.

OVO, did but they have pulled the Heat Pump add on, and their rates are way above others.

Cheers in advance.

Welcome to the forum.

This sort of thing gets discussed now and again; see for example this thread from the Geen and Ethical sub-forum:

A popular option is Octopus Intelligent Go in the winter, Octopus Flux (or Intelligent Flux, if you have a compatible battery) in the summer.

What make & model is your battery? Is it big enough to run your heat pump all day?

Only the one EV here but otherwise much the same.  I haven't seen a tariff pitched at people with both an EV and a heat pump.  I use the Eon Next NextDrive tariff but it has recently got worse, cutting the cheap period from 7 hours down to six hours and jacking up the prices so I wouldn't recommend it any longer.  Their feed-in rate of 16.5p per kWh wasn't bad, if they haven't changed that. 

One thing I do is to make sure I heat my hot water during the cheap EV period.

The key question is always 'How big is your battery?', followed by how much power do you use each day?'.

You are unlikely to find a tariff that is perfect for both ASHP and EV as they have  conflicting needs, but with a large enough battery in the mix you can bridge the gaps.

Then just decide if you have enough battery to cover the majority of the day outside a 5/6 hour cheap rate on an EV tariff, or with a smaller battery if you can bridge the gaps between several low-rates on a heat pump tariff, and just have more complicated EV charging...

I am myself thinking of a battery as I work from home. The issue and why I am waiting is that the current range of batteries safety advice suggests an outside insulation. That doesn’t work for me and I am thinking the sodium batteries that are starting to roll out might be a better bet. So this leaves the inverter in outside storage area.

Many of us have batteries installed inside the house, and personally it isn't something I felt any need to worry about. 

Also you will often find the inverters, which are not always integrated in the same package have the lowest IP rating so putting them outside is not always a good option.

We have 2xEV, ASHP.UFH & 5kW Solar on Octopus Intelligent Go

In summer the solar charges the cars and we have no/minimal export. In winter we run the ASHP at night during the IOG core hours as house is insulated well enough to hold the heat all day

Currently average about 10p/kWh
