Biomass Boilers

In short, biomass boilers mean no more oil, electricity, or gas. Coupled with the opportunity to source local, sustainable fuels, you’ll also improve your price and supply security. 

Indeed, in rural areas, a biomass boiler is frequently one of the most cost-effective, efficient and sustainable methods of heating.

Renewable Heat Incentive for 20 years

Another key point is that biomass boilers qualify for the Government’s Renewable Heat Incentive (RHI) scheme. Currently this runs for 20 years. In other words, for the duration, you’re paid RHI income. Moreover, this can be significant.

That’s of course, in addition to reduced fuel bills and reduced Climate Change Levy (CCL).

Replace your old boiler, keep your RHI rate

At the same time, you may now be able to replace your inefficient, ageing biomass boiler and keep your current rate of RHI. By all means, contact us to see if you qualify.

Modern biomass boilers – peace of mind

Significantly, you can ‘fire and forget’ with modern commercial biomass heating. For example, a pellet boiler, or wood chip boiler. Coupled with our 24/7 service, you can relax and stay warm.

In fact, your plant can even be remotely managed. Not to mention fuel deliveries made to your store, without your attention.

What’s the best biomass boiler make?

The first thing to remember is that IU Energy uses technology brands selected for reliability, longevity, product range and warranty. Indeed, in general it applies in this case to all our renewable and energy saving brands.

For your commercial or domestic biomass boiler, we choose ETA. We are a fully accredited partner of Innasol, ETA’s exclusive UK distributor. Not only does ETA meet our demanding criteria, but they also enable us to remotely check all our installations. This ensures we are aware of any developing problems before our clients.

Below are case studies for projects we have conducted in commercial and high-end domestic biomass boilers, followed by FAQs.

FAQs

By switching to a biomass boiler from a fossil fuel source such as oil, you could expect to see fuel savings anywhere between 30% to 50%, or even up to 80% if biomass is replacing electricity for heating. Biomass is organic material derived from organic sources such as wood chip, wood pellet, logs, grains, straw and miscanthus – all typical fuels. Biomass energy is therefore, produced by burning these biological materials to provide a renewable and sustainable source of fuel. Of all the biomass material, wood fuel remains the most commonly used form in biomass boilers.

Many businesses can burn by-products produced on site, such as pallets and wood off-cut. This not only provides some businesses free fuel, but also removes disposal costs associated with waste removal from site.

Renewable Heat Incentive (RHI) is a UK Government scheme set up to encourage uptake of renewable heat technologies amongst householders, communities and businesses through financial incentives. There are a variety of tariffs, some of which are illustrated here. There are a few qualifiers:

  • Your biomass system must have been installed after July 15, 2009.
  • Emission levels must be below a maximum 30g/GJ Particulates and 150g/GJ Nitrogen Oxide; and
  • Installations below 45kW must be Microgeneration Certification Scheme (MCS) accredited.

Commercial biomass boilers qualify for 20 years of RHI payments, paid quarterly. A tariff level will be assigned to your installation based on its technology (e.g. biomass, heat pump, solar) and size.

Payments will be made based on the actual heat output of the installation and begin to accrue from the date of accreditation of the installation.

Whilst biomass heating systems will cost more than the equivalent fossil fuel boiler, there are significant financial benefits by opting for biomass, with a typical installation seeing a long-term return on investment of around 20% for 20 years. That’s far better than leaving your cash in a bank.

Yes – this scheme came into force on the 1st October 2018. You are now able to continue to claim non-domestic RHI if you replace your biomass boilers ‘like-for-like’. ‘Like-for-like’ refers to technology type and capacity. So, you can install replacement biomass plant to replace a boiler that is causing you problems. But you will lose your RHI if you switch technologies, for example from biomass to ground source heat pump, or heat pump to biomass. 

  1. Small non-domestic biomass – solid biomass including solid biomass contained in waste – less than 200kWh
  2. Medium non-domestic biomass – solid biomass including solid biomass contained in waste – 200-999kWh
  3. Large non-domestic biomass – solid biomass including solid biomass contained in waste – 1,000kWh 

As a guide based on the current rates, a country estate with main house and offices converting to a 200kW heating system would receive approximately £18,151 for the first year and a total of £441,015 over 20 years. A farm house with cottages and a holiday let using 100kW system would earn upwards of £9,075 annually and £181,500 over the duration of the scheme. The tariffs are reviewed every three months and are adjusted based on the increase or decrease in the Consumer Price Index (CPI).

As for a large commercial drying system with a boiler size of 1MW and 75% of run hours at full output, it would generate a significant RHI income over 20 years. For the first year alone, the RHI generated would be approximately £163,637. Over the course of the scheme, the income would equate to approximately £3,975,944. It is easy to see how the project would pay for itself many times over, whilst continuing to generate a healthy income for the business for 20 years, reducing the overall and ongoing carbon emissions significantly, as well as helping the UK achieve the targets as set out in the Paris Agreement.

ROI varies based on numerous elements including project cost, boiler size and usage. Figures quoted are an estimate average and is by no means a guarantee.

Very probably. Please contact us for a site survey.

Nowadays, biomass boiler technology is extremely reliable, and IU Energy recently installed the 4,000th ETA biomass boiler in the UK. With automatic fuel feeds which allow lorries to just drop a fuel load into a hopper and remote monitoring and control, a modern ETA biomass boiler is no more of a challenge to run than your gas boiler, but with massive environmental and cost benefits.

IU Energy is renowned for its 24/7 response and planned service packages. We are the ‘go to’ guys for fixing the installations of other companies when they find that they can’t get older plant going after a breakdown. By installing the very best technology and using our own engineers, we have a tight control over quality – which in this case means demonstrable reliability.

Yes, and that includes underfloor heating.

Yes – we have made installations in places like Crealy Theme Park & Resort and Hendra Holiday Park.
