Any suggestions?

I live in a flint cottage which was built in the 1800’s , I am just about to have the roof re slated and soar panels and Tesla battery storage fitted , I am currently using an oil fired Combi boiler for heating and hot water, the boiler a Worcester Bosch is now over 20 years old , and I am looking to replace it , so my question is what do I replace it with, a heat pump I have been told will not work efficiently in my house , so do I go electric, or oil again baring in mind oil prices are never going to reduce in price?

Direct electric heating with an electric boiler will bankrupt you.

I'd suggest getting a quote for a heat pump, and let the experts tell you if it will work or not.

If it works for the National trust in a 16th Century stately home, I can't see why it won't work for you.

Fitting a new oil boiler is (in my opinion) really only worth doing if the heat pump option is impractical.

Kerosene prices here are on a par with natural gas...  (Around 51-52p/litre.  = 6.1 p per kWh inc vat and 90% boiler efficiency).

ASHP will require an unvented Domestic HW storage tank... You can't do instant water heating.

Insulation can be added / improved -- double / triple glazing as well ---  radiators can be replaced to give similar heat out at lower CH water flow temperatures.  (Plus ASHP designs are improving to work efficiently at slightly higher water temps,  I believe.)  

You are proposing a new roof = You MUST improve insulation to the current latest standards under Building Regulations so that will help.  {AIUI one can't just re-slate / re-tile;  one must upgrade other aspects of the roof.}

Thus there's no reason to not call in a few reputable ASHP installers to quote for replacement... and they will have to do the heat loss calculations as part of the full design process. Note that ASHP will be on a par cost of energy wise cf Kerosene at best... But with a grant towards installation and a new boiler needed sooner or later it may be quite similar Capital outlay.

If the ASHP installers all say it's not economical or possible then a new oil burner will be the way to go.  1:1 electric heating is going to be stupidly expensive at whatever today's price is - 25p/kWh?

I probably would not have posted if the title said what this was about, but now that I am here I will say "if it ain't broke don't fix it", I am referring to the boiler. 

If we were in Australia and had their sun I would be very interested in projects like those on HP Powerwall YouTube channel, I do recycle old 18650 cells but only use them for small projects.

I have followed the alternative heating methods with heat pumps etc and based on anecdotal comments it seems to me that they just fail to make financial sense.  Owners say they do not feel "warm as toast" and some say they have had to get electric radiators on top (defeats the object).

Unless the Gov gives much more generous (and life long) scheme I would advise you get gas if you can, they are the most energy efficient and bizarrely make the energy performance certificate better.

I imagine that you probably do not have Gas as an option so the extra pricing is just a cost of having such a property.  I grew up in a house that was heated by oil, we had half a dozen 1.5m gas cylinders too, oil always seemed tedious, deliveries not timed, people stealing the oil and the cost.

Why unvented, by the way?
