I am looking for someone to repair the glass in my wood burner and also convert my water heater to an electric one. Can you help?

We recently bought a property in Mijas Golf and as with any property it needs a couple of things doing to it. Our water heater is run off a gas bottle and frankly doesn't get the water above lukewarm. Fine in the summer but freezing in the winter!!! Others we spoke to in the summer have   converted to an electric water heater which I think would suit us better. Does anyone know who could do this for us?

We also have a wood burner which has a crack in the glass so we would also like to get this repaired but are again struggling to find anyone    who can do this.
