steam boilers guide: best condensing steam boilers prices list

The average cost to install or replace a condensing steam boiler starts at $2,500 and can reach as much as $11,000 depending on the model you choose and scope of work involved in the installation. Most homeowners spend $4,500 – 8,000 to install a condensing or a combi boiler.

Condensing steam boilers are an efficient way to produce hot water and central heating. They’re popular with homeowners and builders because they’re more energy-efficient than traditional boilers, but they also have a wider range of uses. This article will explain how condensing steam boilers work, how much they cost, and whether they’re right for your home or project.

What is a condensing steam boiler?

A condensing steam boiler is a type of steam boiler that uses a heat exchanger to recover the latent heat from the high-pressure exhaust gas leaving the engine, which can then be used to preheat combustion air or feedwater. This reduces fuel consumption and emissions, while increasing thermal efficiency through better recuperation.

Most industrial boilers are designed to operate in conjunction with an auxiliary cooling tower (AC). The AC cools off water produced by evaporation in its wet process operation and supplies this water as make-up flow for partial cooling of condensate. The resulting cooled combustion gases are routed back through the furnace into what would otherwise be dead space between tuyeres, re-heating them before exhausting through flue gas stack(s).

Q What kind of fuel does your boiler use?

How efficient are condensing steam boilers?

High Efficiency Condensing Steam Boiler

Condensing steam boilers are more efficient than non-condensing boilers, but they’re not as efficient as condensing hot water boilers.

A condensing steam boiler will use about 95% of the energy from its fuel. A non-condensing steam boiler will use about 80% of the energy from its fuel. In comparison, a conventional open fire or electric storage heating system uses only 60% to 75% of their available energy for output heat because much is lost through air convection and radiation, while conduction through floorboards or walls also takes some heat away before it gets into rooms where people can feel it. A typical room radiator uses only 30% to 40% of its available input energy due to convection losses in adjacent rooms (through shared walls) and via radiation into living spaces when closed doors are used instead of open windows on colder days when temperatures fall below comfortable levels indoors (which happens when you’re using an electric storage heating system).

Are condensing steam boilers expensive to run?

condensing steam boilers run cost

Once you have a condensing steam boiler, running costs are lower. This is because of the following:

  • No need to vent steam to the atmosphere
  • No need to replace flue pipes
  • No need for a chimney or air dome

Advantages of condensing steam boilers

best condensing steam boilers

Condensing steam boilers offer many advantages over other models, including:

  • Reduced fuel bills. As the condenser recovers heat that would otherwise be wasted from the flue gases and transfers it to the water in the boiler, this reduces your operating costs.
  • Lower emissions and better for the environment because of less pollution being emitted into atmosphere. It also means you won’t have to worry about costly environmental fines.
  • More efficient operation as energy losses are reduced through thermal efficiency increases from 75% to 90%. This means higher output levels at lower running costs with much less maintenance required than conventional designs which require regular inspection/cleaning along with regular filter changes on a weekly basis due to scale build up within their pipes & heat exchangers – all adding up to greater overall costs over time compared against models such as these where maintenance requirements are much lower overall!

How much does a condensing steam boiler cost?

condensing steam boilers prices

Condensing steam boilers are the most efficient way to use your fuel and they can save you money on your bills. The best part is, they are also very easy to install so you won’t need any additional help.

The price of a condensing boiler will depend on which type of boiler system you choose, how much power it produces, and if it uses renewable energy sources such as solar panels or wind turbines. If you decide to upgrade from an old heating system that doesn’t use renewable energy sources then your new boiler could cost approximately £2,500-£5,000 for a standard 3kW model. A larger 5kW condensing water heater would cost around £3,500-£6,000 depending on whether it’s gas or oil fired and whether there are any extra features included such as solar panels or biofuel tanks attached to the unit itself.

If upgrading isn’t necessary then installing one could still save money over time because they use less fuel than traditional systems while producing enough heat output during cold months so there aren’t any interruptions in service throughout winter months!

How much does a condensing steam boiler cost to install?

condensing steam boiler isntall cost

The cost of installing a condensing steam boiler depends on many factors. The size of the boiler, the complexity of installation, location and whether it is a replacement or new installation all affect the price.

The price will also be affected by whether you’re dealing with an experienced installer or not. You should expect to pay more for an experienced company than one that has never installed a steam boiler before.

The cost also depends on whether you’re looking for a simple replacement or a more complex installation. A simple replacement can be done in as little as one day and shouldn’t cost more than $1,500. If you need to upgrade your system completely, the price can reach up to $5,000.


In short, a condensing steam boiler is a great investment that can save you money on your energy bills. It’s also more environmentally friendly than traditional boilers because it doesn’t emit greenhouse gases like carbon dioxide into the atmosphere. If you’re planning on installing one in your home or business, we recommend getting quotes from as many contractors as possible so that you can compare prices and get an idea of what kind of return on investment (ROI) each contractor offers before making any final decisions.
