Looking for an affordable alternative to electric storage ovens

I am the landlord of a multi-family house heated by electric storage heaters. The tenants are increasingly complaining about the rising heating costs and are demanding an alternative heating option. What is recommended with regard to the future? What will probably be the most cost-effective way to heat in 10-20 years? I am concerned about the long-term costs, less about the one-time investment in a new heating system.

There are two ways to permanently reduce heating costs: 1. Keep heat loss as low as possible; this may mean investing in insulation for the facade, the roof, and new windows. 2. Install an efficient heating system. Efficient means using the heating or fuel as effectively as possible. This could be a gas condensing boiler, a heat pump, a small combined heat and power plant, or a modern wood pellet heating system. What the best method or combination of methods is for your house must be determined on-site by an energy specialist together with you. This includes everything from the most suitable technology to a financing/amortization plan to finding possible [stated] subsidies.

Hello,

So for me these electric storage heaters are out. Electricity for heating is just way too expensive. The previous writer pointed out which measures are necessary to dramatically reduce energy costs. But it doesn't work without that either. That's clear too, it all costs money.

Nice that for the previous posters BG& HB-F electric storage heaters are nothing. But in the case of the OP: Does he have a higher six-figure sum ready not only to provide new insulation (which already makes sense!), but also to install water-bearing radiators in the apartments? Laying water pipes (chipping walls), space for boilers, pumps, etc?
How will the tenants think if the additional costs (electricity) decrease, but the rents increase?

I assume that it is not water heated with electricity (which is really easy and reasonable to replace), but that there are simply no water pipes.

Hi,

That is correct and must be taken into account. These renovation works including thermal insulation are an expensive matter. Often new windows also have to be installed. Then the monthly rent increases significantly and the tenants will not be happy about that either.

That is simply too expensive and I cannot imagine it in the long term either. There are many alternatives and here a wood heating system can save costs in the long run.
