New heating system but struggling to get the right tariff

Hi Everyone,

Thank you to all those who helped last year regarding Air Source heat pump as my oil boiler went down and i was having trouble with my housing association about when it was going to be installed etc. That was in May last year.

 

Fast forward to this year we now have a heating system ....its Storage heating and I spoke to OVO regarding all this being changed in January this year apparently yes then at the last hour it was no. Ok so I tried to look for a different company that do Economy 7 tariff.

 

Found one but now OVO don't want to let me go due to a huge bill which I have due to it being wintertime and having to use electric heaters due to no heating system can anyone advise  me what to do obviously I didn't really want to leave but ....its a case of having to but then if OVO did Economy 7 or something similar I wouldn't have to.

​... will Viv1966 be able to get a duel tariff like Economy 7 with the meter setup they have ?
  

If you’ve been advised that we can’t switch you to Economy 7 (which is generally the case) 
 

We can’t tell whether this meter is capable of switching an offpeak circuit on and off. Even if it did have the internal switch necessary, there would have to be an external contactor to do the actual power control.

It seems that the magic use-excess-solar-generation-to-charge-heaters system only works if the heaters are wired to a constant circuit (i.e. not having the charging bit separate from the control bit so charging only happens during offpeak hours). Again, we can’t tell whether this is Viv’s arrangement. It involves installing some extra bits and bobs including a CT clamp, all included in the optional Solar Box.

 

 

As ​@Firedog suggests, a separate supply is not needed for these 

So that should mean that a traditional 4 terminal smart meter should work with these heaters.

The balance would then be how much energy is needed during the day for other appliances and how the units are connected

@Viv1966 please could we also get some photos of your heating system.

 

Please could you also let me know - is there just the one consumer unit (fuse board) in your property?

@juliamc  Thank you for your explanation of Solar Panels .....! I registered them on 10th April so at the end of this week beginning of next i should be registered with Octopus with Solar Panels  they offer about the same price as Ovo. I am sorry to sound stupid but  how will i know my electricity  is working from the Solar Panels will it show on my app? Or will my electricity be noticeably cheaper i have to say i am a bit green when it comes to things like this!

Hi ​@Viv1966, thanks for sending this in.

 

I’ve checked the website of the heaters which says:

 

The PH PLUS programmable wall-mounted convector heater can heat any room very quickly. It is highly recommended for use at specific times throughout the day, for occasional use in certain rooms that do not have heating, or to supplement other heating systems already installed in your home that don’t provide sufficient heat on very cold days.

 

This convector is available in 4 models with different powers, ranging from 750W to 2000W, to provide the necessary heating for the square metres you wish to heat.

 

PH PLUS convector heaters integrate an ETCO electronic control optimizer that manages and restricts the flow of electricity based on the information offered by the high-precision thermostat. In addition, they are fully programmable, daily and weekly programming with 48 manoeuvres per day. In each of them it is possible to assign one of the three temperature levels: Comfort, Economic or Anti-ice.

 

I am no expert in different types of heating, but I’m thinking that these aren’t storage heaters, in that they don’t store energy overnight and release it as heat during the day. I believe these heaters act like a panel heater, and can be used whenever you wish to heat up a room. If this is the case, then Economy 7 will not be the best option for you, as you’ll be using these heaters on a more expensive day-time rate than you would be at the moment. 

 

It might be worth calling Elnur (the manufacturer) for clarification. They can be reached via phone (01942 670 119) or email (technical@elnur.co.uk). I’m cautious of giving you advice on this one as I haven’t seen these heaters before, but hopefully the manufacturer will be able to tell you the proper information. If you do speak to them we’d appreciate it if you’d let us know what they say.

 

Please note - switching to Economy 7 shouldn’t be done lightly - this can end up being a costly mistake if the household appliances are not set up to benefit from it.

@Ben_OVO the first manual that Viv1966 posted is a storage heater which is said to also store excess PV production. I’ve not seen these before but Google says “They combine automatic charging for off-peak tariffs (like Economy 7) with solar self-consumption...”. Viv1966 has three of these as well as the one convector heater.
