Steam Boiler Costs - 2020 Buying Guide - Prices -
Steam boilers are a type of boiler that has been in use for hundreds of years around the world. The average cost for a steam boiler is about $4,000.A higher end steam boiler installation could cost up to $7500. Steam boilers rely on simple mechanics, which make them so reliable to work with.Still, they aren't particularly efficient or quiet compared to hot water boilers on the market today.

Is hot water really more efficiant than steam? —
Hot Water Vs Steam Hot water is more efficient than steam, but there are considerations. Don't just look a boiler efficiency as a stand alone factor. If you think of a boiler as a heat exchanger (which is all it really is, when you get right down to it), you can have lower flue gas temps for the reason you stated.

The Basics of Industrial Steam Boiler Systems | Miura
The boiler requires an hour or more to power up and down no matter how much steam is needed from moment to moment. However, with a modular configuration of smaller water-tube boilers, the boilers can power up and down in direct response to fluctuating load demands, resulting in a much more energy-efficient and cost-efficient operation.

How Efficient is a Condensing Boiler? (2021) |
Thus, a condensing boiler will be more efficient if it is coupled with water-based underfloor heating with the flow temperature of 40 to 45 degrees Celsius. Since there is no recommended minimum temperature for the coolant, a boiler that is connected to an underfloor heating system can work without special temperature-lowering devices.
