One of the most important questions for any renovators and self-builders is that: How can they design the most energy-efficient heating and cooling system in their new house? In fact, this is a complex task, so it is better to consider the following important factors.
- Heat demand
First, it is necessary to measure the heat demand for all rooms in your house. This might tell you the exact size of pipe runs or radiator needed for a heating system. In addition, it would suggest the locations that need to be improved if you are planning to design a system for the current house.
There are a couple of online calculators available, but you should use them carefully. In most cases, they require the least information and measure standard levels of insulation and construction. Even though these applications offer a helpful initial result, the final recommendation should be performed by a professional.
- Methods of heating distribution: Radiators versus UFH
In this case, it is just the matter of personal preference: The radiators are a bit more expensive to operate, while the UFH is a bit cheaper to set up. However, the main difference lies in the way two methods control.
Another important factor to look at is the radiators’ location. When the heating air meets a window or cold surface, it might get cold and fall to the degree that it gets a draught. This is the reason why radiators are often placed under a window. However, this is not a problem with an underfloor heating and cooling system since the hotter increasing tends to eliminate the cooler air decreasing.
- Weather compensation
As the weather always changes, it is important for a heating system to adjust frequently to make your house warm adequately. In general, a good heater will address this problem with a weather compensator. The mechanism is simple: a built-in sensor will register the current temperature outside and adjust the heat provided to your house.
The issue could be with the sensor’s location. This element is often installed on the outside wall that is near to the boiler, but it actually needs to be placed on a south-facing wall to get out of the dominating wind.
- Heat source
A common question that many homeowners often ask is whether they should use a heat pump or a boiler. In addition, it is possible to use a completely solar-heated system, but it needs the help of an experienced electrician. These days, solar energy is a new trend that should be added in nearly all new-build designs simply it is more environmentally-friendly and energy-efficient.
Your decision over the right heat sources would mainly depend on all factors mentioned earlier. Thus, there will be no right or wrong choice but going through the whole process might result in a better decision for your task. There are some cases that can help you exclude options:
– If the main gases are not available currently, the expense of buying a pipe laid could be very high
– The excessively changing cost of heating oil makes it a good decision, at best.
– The necessary work for a biomass boiler might be not practical
– Lack of garden space might exclude a heat pump that comes from a ground source.
