Pain points
Boilers often serve mixed temperature loads through a single high-temperature network. This makes every low-temperature user dependent on fossil fuel.
Replacing a boiler one-for-one can preserve the same inefficient architecture.
Decision framework
Segment users by temperature, schedule and criticality. Convert low-temperature users to hot water. Recover heat where possible. Use heat pumps for continuous low and medium-temperature demand. Keep direct electric or hybrid systems for residual peaks where justified.
Engineering FAQs
Is an electric boiler a good replacement?
It can be useful for residual steam, backup or peak heat, but it is rarely the most efficient answer for low-temperature continuous loads.
