Servicing and Repairs

We’re here to keep your renewable energy installation working in tip top condition.
Every time we see your renewable energy installation, it will get an Alt-Energi Visual Check (AVC),
regardless of when or who installed it.

The AVC enables us to fully understand how your system is running and any unique customisations of your installation. The check will give our customers peace of mind that the system is running efficiently and that metering is meeting the Renewable Heat Incentive mandatory requirements.

We will provide a report on the installation which will be completed by our trained engineers.There may be issues that need attention immediately or there may be issues that you need to made aware of for future attention.

Repairs may need carrying out between services and the team at Alt-Energi are always ready to help. You can call us at anytime on 01527 864232 to arrange for repair work to be carried out.

Alt-Energi have a range of Service and Maintenance Plans to suit your installation. These plans are tailored to you needs and help us to take really good care of your installation whilst keeping costs affordable and predictable. Click here or on the installation that is relevant to your installation, complete the form and we will be in touch to create the right servicing and maintenance plan for you.



The amount of attention your biomass boiler needs will depend on the model and the type of fuel you use. Wood logs, chips and pellets all burn in different ways and create different amounts of waste – and some high-end biomass boilers have extra features which mean they can look after themselves to a certain extent.

In order to keep your system running efficiently and to ensure a good return on your investment, it is important to provide adequate maintenance. The following gives you an idea of what you will need to do:

Daily – It’s a good idea to visually check your boiler for any obvious signs of wear and tear and clean any components that are easy to get to. Leave the tricky areas to us!

Weekly – Check the ash level and empty if necessary. Check gear motors for oil leaks.

Monthly – Scrape the combustion chamber and remove any bad ash (clinker) which can build up if the fuel has been not at the right moisture content, or if the boiler has not been burning at the correct temperature. Also check grates for any residual ash not clearing itself properly.

3 Monthly – Wipe the flue gas sensor, clean the ignition probes and check the grate and mechanisms.

6 Monthly – Check and clean the flue gas return, inspect the operational drives, check the motors, clean the heat exchangers and clean the combustion chamber.

Annually – This is usually carried out your installer or our team at Alt-Energi. We have a 70-point check list which thoroughly checks your boiler including cleaning the flue and greasing the bearings.

solar-servicingThankfully, since there are no moving parts, solar panels require very little maintenance. Once you have covered the installation cost of solar panels, there are not many costs associated with maintaining them.

Having said that, you should inspect them a few times per year for dirt or some other things that might have piled on top. It is important that the panels are clean and there is nothing blocking them from efficiently absorbing the sun.

Before cleaning the panels yourself, you should consult with your installer about the warranty conditions. Some solar panel manufacturers could terminate the warranty if any self cleaning is done.

For a general cleaning, you can just use a normal garden hose to wash the face of the panels. You should do this in the morning or evening. Also avoid spraying them with cold water while they are hot because that might damage them.

Tips for Maintenance of Solar Panels

Watch out for shade –  Keep solar panels out of shade as energy production becomes inefficient when they are kept from absorbing any sunlight.

Keep an eye on the solar panels and make sure the inverters are flashing green lights – If they are not flashing, you are losing money by no longer compensating for your electricity use.

Document the day-to-day performance to improve solar panel maintenance – It is important to write down how much energy has been produced at a consistent time every day and make special note of dates where it is very cloudy. Some of the results will be inconsistent. (Your manufacturer would be able to provide you with the best monitoring system for your solar panels.)

Monitoring systems help you see how much you are benefiting the environment – and how much CO2 you are emitting into the atmosphere. They can also help you know how much you could benefit from the feed-in tariff scheme.

You should have your system examined every 4-6 years by an installer. It is also a good idea to ask your installer about specific maintenance requirements for your solar system.

Alt-Energi provide a stringent maintenance service program for all our ground source heat pumps. It’s important to maintain the system correctly to gain the maximum benefit from the Renewable Heat Incentive. A 5-10 year warranty on parts and labour is standard, and we expect systems installed by us to last at least  20-40 years and probably many more if properly maintained. The annual service by our team of engineers which covers theses areas:

  • The electronics and control equipment
  • The water pump – the only moving item in the system
  • The compressor – if this unit fails it will have to be replaced as a whole as it is a sealed unit
  • Pipes and connectors (above ground)
  • Anti-Freeze / coolant fluid in the ground array – check for correct chemical mixture
  • Heating checks – check radiators and bleed system / check fluid.
  • As with all devices containing or designed to contain F-Gas refrigerants, an ‘F’ Gas certified engineer will be required to work on these components.
