Frequently Asked Questions

Yes, where possible we can arrange for you to collect your items. In some cases, your items may be sent direct from our suppliers or they may be sent from our different warehouses, so in these cases, it may not be possible for you to collect your complete order. For more information, or to arrange a collection, please get in touch.

As many of our products are stock items, we look to offer next day delivery when possible. Our standard next day charge is £15 with additional charges for pre-9am, pre-10am, AM or Saturday delivery options. Some items have longer lead times and may incur additional delivery costs, for instance if your address is outside of mainland UK. Please contact us for further information.

Product Specific FAQs

Air Source Heat Pumps

All heating systems make some noise, but air source heat pumps aren't any louder than the heating systems you're used to. Having said that, if your heat pump is installed poorly or incorrectly, it will produce more decibels than it should. An air source heat pump should reach 40 to 60 decibels, varying by model. Upon installation, the professionals involved should conduct a noise assessment to ensure that the heat pump doesn't disturb homeowners or neighbours.

In the UK, the answer is typically no. It might be considered a 'permitted development,' meaning you won't require permission. However, always check with your local council first to ensure the installation is problem-free. You can find guidance on the planning portal website.

If installed correctly from the get-go, it's reasonable to assume the system will run for 15-20 years and longer in many instances.

Like any thermostat, you can programme the heat pump to provide heating or cooling (depending on the model) at specific times. Yet, running a heat pump consistently at a low temperature is better than on/off schedules. The system will use less energy to maintain a temperature than letting it go cold and reheating.

However, suppose the property needs to be better insulated and is drafty. In that case, it's reasonable to assume that running the system long and low will cost more money than only heating when required because the heat escapes quickly

Ground Source Heat Pumps

Your location and space may answer this one for you. Horizontal systems, and trenches, are only viable in large outdoor areas, so rural locations usually opt for trench installation. Trenches are cheaper to install. Boreholes, or vertical systems, are more expensive but better suited to smaller outdoor spaces.

The area required for trenches depends on the peak heat demand for the property being heated and the thermal conductivity of the ground. Information can be found on the BGS website.

Boreholes are typically 80-100m deep, but again this will depend on the geology and heating demand.

The boreholes are spaced a minimum of 6m apart and typically use a 150mm hole.

If you were to opt for a trench installation, this is the question you may pose to yourself next. Slinkies are coiled plastic piping lengths, much like a slinky toy, but laid flat within the trench. The trenches are spaced apart to avoid over-extraction of energy from the ground. 2-300m of pipe should fill a 50m trench.

Slinkies require less digging than straight loops. They cover a similar ground area to straight loops but are more convenient for obscurely shaped land.

Straight pipes sit in narrow trenches and stretch much further. Yet, they can be dug closer together. They are just as efficient.

The UK government plans to dramatically reduce carbon emissions over the coming years, focusing heavily on heating systems. Gas boilers are powered by fossil fuels, contaminating the planet's natural resources and creating vast amounts of pollution. Heat pumps, on the other hand, do not emit harmful pollutants.

Efficiency is where they differ too. A gas boiler is around 90% efficient, wasting 10% of its power. That's 10% that isn't heating your home. Ground source heat pumps typically offer 300-400% efficiency, three to four times the electricity required to stay powered.

Dependent on the model, any heat pump can provide either passive or active cooling. Passive cooling refers to the heat pump using the cooler air temperature to cool the heating emitter system. The system works by circulating the two fluids via a heat exchanger, essentially not using the refrigerant circuit in the heat pump. Active cooling refers to a reversed system, where the pump extracts heat energy from your home and draws that into the ground, rather than the other way around in heating mode.

Energy Blade 3K4

Yes! You can connect up to four in a series. A single Energy Blade (set of four) has been designed to run with a flow rate of 1.2 l/s to give a design flow-return temperature spread of around 3oC and an acceptable pressure loss when using 25% by volume propylene glycol. The flow rates should be doubled for two Energy Blades connected in series. You can install as many as necessary as long as the brine circulation pump can overcome the pressure drop.

No! With our MCS Umbrella Scheme, we can oversee the energy blade and heat pump installation. Contact us today for more information.

Energy Blades are suitable for use in freshwater. They should not be used in salty, sea, or corrosive environments. Energy blades are made from stainless steel 316 and are still suitable for many moving water applications.

Energy Blades are intended to be used and perform best when fully submerged. Accumulation of silt, weed or debris will adversely affect the performance. We recommend that Energy Blades should be inspected periodically so that silt and debris can be cleared. We recommend an annual check and clearance wherever possible.

Solar iBoost+

If left without specific programming, the iBoost+ requires a minimum of 100W before energy is diverted to the immersion heater. If you have home battery storage, you can decide how you wish to programme self-consumption depending on the cut-in threshold of your battery.

The product is designed to be used with a maximum of 2 immersion heaters rated up to 3kW. Immersions need thermostats to operate with the Solar iBoost+, but no electronic controls. A qualified electrician must carry out all installations to avoid damage.

Using the iBoost+ built-in display, you can see exactly how much energy you have saved daily, monthly, and beyond since you first had it installed. View your information from anywhere in the house using the iBoost Buddy accessory.

The Solar iBoost+ has both a Boost and Programme function. Receive instant energy from the grid as each time you boost adds 15 minutes of operation. This function stops once the thermostat reaches your desired temperature or the selected time is up. Alternatively, the programmable timer can be set to use grid power only.

Cylinders and Buffers

A buffer tank is expected to live as long as the rest of the heating system — 20+ years, depending on the system's water quality

Yes! There are many different types and models, and the warranties vary, so enquire today to find out more.

A large majority of heat pumps now modulate to suit the demand of the building, but in warmer weather, when buildings only require a little heat, the heat pump can short cycle, switching off and on frequently and creating wear on the compressor. A buffer tank can help overcome the issue.

Buffer tanks can also be used to store heat energy, self-generated or generated during times of cheap electricity to be used later in the day without the heat pump needing to operate.

Generally, you add 15-20 litres of water per kW of minimum heat pump capacity; this should prevent short cycling and satisfy defrosting on an ASHP.
