Emergency boiler repair? An opportunity in disguise!

A boiler that breaks down at the start of a new heating season is far from ideal. However, what’s often viewed as a setback is actually an opportunity in disguise. As we see it, an emergency boiler repair is a great opportunity to revise the entire heating system and opt for durable low temperature heating, without the hassle and significant costs of a complete energy renovation. The same applies to boilers at the end of their service life. Especially taking into account the sharply rising energy prices and the need for energy efficiency that has never been greater.

New boiler? Don't forget the radiators.

Any HVAC professional knows that in order for a heating system to run efficiently it must be considered as a whole. Only when the individual components that generate, distribute and emit heat are fully coordinated, can the heating system function properly. So when a new boiler is installed, the distribution and heat emitters should be reviewed as well. Since radiators are still the most commonly used heat emitters, new radiators make the perfect renovation duo with a new boiler for the optimal functioning of the heating system.

Especially in properly insulated buildings this is a great opportunity to switch to a low temperature heating system. Low temperature heating significantly reduces energy consumption, which saves money and reduces emissions. That’s a win-win for the end user and the planet. Low temperature heating can also be installed in poorly insulated buildings. However, in this case, the radiator output must be increased to guarantee indoor climate comfort.

Low temperature radiators

As the overall success of a new heating system depends on good planning and a professional installation, HVAC planners and installers play a key role in the transition to low temperature heating. Considering old radiators were designed for high system temperatures, this includes the switch to compatible heat emitters such as modern low temperature panel radiators or fan convectors. Thanks to modern heating technology, these provide the required heat output and ensure optimal indoor climate comfort. To easily calculate the heat output for any of our radiators, simply select it in our heat output calculator and enter the parameters applicable to your project.

Modern heat sources operate at lower system temperatures for improved energy efficiency. Since the old radiator isn’t able to provide the required heat output at lower system temperatures, it must be replaced with a modern radiator which can generate the necessary heat output with almost the same dimensions.

TIP: Today’s radiators are not only more advanced, they also come in a wide range of shapes, colours, materials and dimensions. Ranging from standard panel radiators to designer radiators, there are countless options available. So don’t hesitate to browse the entire radiator collection and select the ones that are a perfect match for the interior concerned.

Heat pump paired with radiators

One of the advantages of low temperature heating is the fact that it can be combined with various heat sources. While it’s perfectly possible to use a condensing gas boiler, you can also swich to renewable energy with, for example, a heat pump. Since radiators are a great match for both boilers and heat pumps, home owners are free to choose their energy source and don’t necessarily have to invest in a heat pump right away. When low temperature or ultra-low temperature radiators are installed, the heating system is ready to transition to renewable energy at any time.

Hydronic balancing

Before running the low temperature heating system, it’s important to make sure that all radiators are supplied with the necessary amount of warm water. Heating systems that are not balanced hydraulically won’t be able to supply enough hot water to the radiators furthest away from the circulation pump, while the radiators near the pump will be oversupplied. This increases both energy consumption and heating costs and decreases indoor comfort, all of which we are just trying to avoid by installing a new heating system. With the right thermostatic radiator valves, hydronic balancing is a piece of cake. A well-balanced modern heating system in a properly insulated building can help to save up to 30% on energy consumption.

Radiator replacement

When it’s time for the actual radiator replacement, the goal is to do it quickly and cleanly, without creating any dirt or noise. Luckily, Purmo radiators offer several practical solutions so that changing radiators is no big deal. For example, with our Compact panel radiators which have been designed to exactly fit the existing pipes or connections for a one-on-one replacement. This way little time is required for the radiator replacement, which can take place while the residents remain in their home.
