What is a hydronic condensing boiler?
Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.
What is the best boiler for hydronic heating?
High Efficiency Condensing Boilers The Ideal Range of condensing boilers are the most efficient hydronic boilers currently available. Ideal condensing boiler technology is the latest advancement in hydronic boiler efficiency.
Are condensing boilers really more efficient?
Condensing and non-condensing boilers both burn fuel, such as gas, but the main difference is that the energy efficiency of condensing boilers is up to 99% efficient while non-condensing boilers are only up to 78% efficient.
Do I need a hot water tank with a condensing boiler?
Condensing boilers don’t necessarily need a hot water tank or cylinder in order to work — that will depend on the type of boiler you have in your home. Combi boilers do not use a hot water tank, but heat only or system models do.
What is the advantage of a condensing boiler?
The main advantage is the boiler’s efficiency. Through recycling waste gases back into the system, a condensing boiler can have approximately 90% energy efficiency. This is vastly superior to the efficiency of a traditional boiler which is typically between 70-80%.
What size hydronic boiler do I need?
An easy rule-of-thumb for BTU requirements is to figure that you need about 50 BTU per square foot of interior space in a cold climate; 35 BTU per square foot in a moderate climate; and 20 BTU per square foot in a hot climate.
Do you need a water tank with a condensing boiler?
Space savings: a condensing combi boiler does not need a hot water tank and is available in a wide range of compact sizes, making it much suitable and convenient to fit in a kitchen cupboard than conventional boiler models.
How long will a condensing boiler last?
around 15 years
Generally speaking, you can expect modern boilers to last for around 15 years, or potentially even longer if you get a good quality model and service it regularly.
Where does the water come from in a condensing boiler?
Condensate is what gets produced when your boiler is being used to heat your home or produce hot water. This is because when your boiler burns fuel, a chemical reaction causes produces carbon dioxide and water vapour by-products. Once enough heat is produced from this vapour, it’s condensed back into water form.
Do you have a hot water tank with a condensing boiler?
What size boiler do I need for a 2000 square foot home?
about 60,000 BTUs
Example: What Size Boiler Do I Need for 2,000 sq ft? So all you have to do is take the square footage and multiply it by 30. If your home is 2,000 square feet than you will need about 60,000 BTUs.
What size boiler do I need for a 3000 square foot house?
Can you have a hot water tank with a condensing boiler?
Do I Need a Hot Water Tank with a Condensing Boiler? Condensing boilers don’t necessarily need a hot water tank or cylinder in order to work — that will depend on the type of boiler you have in your home. Combi boilers do not use a hot water tank, but heat only or system models do.
