If you are concerned with saving money on your monthly utilities, there are a few changes homeowners can make to economise. If you are hoping to save up to 40% on your energy bill, opting for a new, A-rated combi boiler may be one of the better long-term options. This article will cover some basic information on becoming energy efficient, alongside facts in regard to boilers, as well as various, highly rated units on the market.
Improving Your Home’s Energy Efficiency
While it may seem easy to tell someone that they can decrease their home’s overall energy consumption by simply replacing their ageing boiler, it isn’t always that easy. There are a variety of ways to make improvements, if a new boiler isn’t an immediate option for you budget. New solar panels, new or additional attic or loft insulation, upgrading to double glazing heating, and new condensing boilers are a few long term solutions. Short term solutions include:
Energy Efficient Blackout Curtains
New Installation of a Programmable Thermostat
Temporary Door and Window Insulation
Upgrading Appliances to More Efficient Models
Seeking out a Cheaper, New Energy Supplier
The addition or improvement of cavity wall insulation is suggested to prevent up to 35% of energy losses. Typically, this energy escapes through external walls of your average homes, without owners taking much notice. One could theoretically save a tonne of carbon dioxide per every square metre (of insulation), over the building’s lifetime, by adding insulation to outdoor walls.
Why You Should Consider a New Boiler
In general, the type of boiler in your home has a lot of baring on whether or not you should replace your boiler with a newer model, and when. If your unit is around 15 years old, it is a condensing boiler. Anything older than that is, more often than not, a non-condensing boiler, which brings along it’s own issues. Most importantly, non-condensing boilers are unable to recycle waste gases created during use, which means it cannot reuse gases – something condensing boilers offer.
Thanks to the conveniences of modern technology, condensing boilers allow hot gases to be reused for heating water, once it passes through the heat exchanger. The result is a decrease in energy waste, simply because of the ability to reuse produced gases, and, ultimately, lower energy bills.
How Condensing Boilers Save Money and Energy
Manufacturers are always coming up with ways to compete by producing newer models that are less of an energy hog, while also being easier on the wallet. As technology advances, newer boilers consume up to 85% less fuel when compared to non-condensing, over daily use. Combi, which may be confused with condensing, actually refers to the type of boiler. Other types of boilers include: open vent, storage and system. Any Combi installed within 10 to 15 years, will most likely be a condensing.
Well known boiler producing brands, such as Ariston, created a name for themselves by producing efficient boilers. When you consider an efficiency of 85%, every £150 spent creates £22.50 of waste, each month on average. With a year’s worth of seasonal changes in temperature and humidity you will be looking at a larger, overall waste in terms of energy and money alike. Although it largely depends on the type of boiler you own, or have chosen to purchase, new condensing boilers tend to start off in the 90th percentile.
There are other ways to boost a boiler’s efficiency, aside from moving onto an entirely new unit. Installing smart thermostats, utilising power flushes and weather compensation technology are just a few of the ways homeowners may boost a boiler’s overall energy efficiency. If you boost efficiency, up to a percentile closer to 94%, you would only be losing around £8 rather than £22.50. Choosing a well-known brand, one that has made a name for themselves with quality and high efficiency ratings, will do more for your home as a long term investment. For example, a Viessmann Vitodens 200-W boiler, provides an efficiency rating in the 98th percentile. A unit such as this could mean hundreds in savings, off of your annual energy bill.
What are Combi Boilers?
Combi, short for combination, boilers happen to be one of the easiest unit designs to install, operate and maintain. Gas combi boilers are one of the most popular choices across the UK, and it’s no wonder, considering how efficient they are energy and space wise. New technology allows manufacturers to produce less demanding compact models, that provide both heating and warm water. Before combi boilers were introduced, it was rather common for homes to store a separate water heater in another space within the house. Thanks to all-in-one units, homeowners can get more out of their money, and floor space.
Gas combi boilers make the most out of the energy required to heat water, without the need to store and heat more water than is actually required through the day. This kind of boiler generates hot water almost instantly, through use of a built-in, pre-heat system. Most older boilers turn on a burner once per hour to maintain the reservoir temperature, for stored hot water, which runs regardless of whether the tap has been turned on.
Choosing the best size combi boiler for your home is vitally important for the overall function of a new unit. Houses with more bedrooms and bathrooms will call for a larger system than a smaller building – typically 20-35KW for a 3 bedrooms. Larger houses often demand larger boilers such as something between 35-42KW. For bigger homes, though, a system boiler may be a better alternative. The heating requirements and overall demand should be considered when choosing the sheer size of your new boiler, to ensure the proper delivery of hot water and heat.
The Most Efficient Combi Boiler
It’s simple, not every boiler is created equal.
