Proper boiler maintenance in order to maintain peak boiler energy efficiency
Maintaining the boiler at peak efficiency requires keeping the boiler surfaces as clean as possible. As a result, they should be opened regularly for checking and cleaning. Deposits (often referred to as scale) on the waterside of the boiler tubes can impair heat transfer. They can also reduce boiler efficiency, restrict water circulation and lead to serious mechanical and operating problems. Scale causes the tubes metal temperature to rise, which increases the flue gas temperature. In extreme cases, the tubes fail from overheating. Did you know that just one millimetre of scale build-up can increase fuel consumption by two percent?
Having your system flushed annually and treated with descaling chemicals can help to remove scale build up and maintain energy efficiency.
Hydronic radiant heating applications
Hydronic systems like boilers, tankless water heaters and combi boiler systems are great solutions for several different radiant heat applications. There have been several creative uses developed over the years to make life more comfortable:
- In-floor heating can be used either as a site specific solution or througout the entire footprint in liew of wall or floor mounted radiators.
- Heated roofs are a great way of both removing the load from snow as well as increasing the longevity of the roof itself.
- A heated driveway and walkway is just the ticket for never having to remove snow or ice again.
- Towel warmers deliver a nice pampering feature to any bathroom facility, with modern styling to enhance any decore.
