Our Story
BRIEF HISTORY
In 2010 the Qualis brand was formed. Originally only aiming at the commercial solar market. After successfully installing 27MW of solar we took the decision to expand our offering into contract residential renewables. Working for Social Housing Providers and Tier 1 Contractors.
Fast forward to today and we now offer commercial and residential solar, heat pumps and air conditioning to businesses, social housing providers, tier 1 contractors and direct to home owners.
Where we cover the whole country for commercial and contract services, our Qualis At Home, direct to consumer service, concentrates on 5 counties (Nottinghamshire, Yorkshire, Lincolnshire, Leicestershire and Derbyshire) to ensure our able to pay Customers get the service they are paying for.

Do heat pumps work in the winter?
Sweden install over 100,000 air source heat pumps a year!
Sweden is, on average, colder than England, with a yearly average temperature of around 7 degrees compared to England's 10 degrees.
The difference is more significant in winter, as Sweden's coldest month (January, with an average minimum of -6) is much colder than England's (February, with an average minimum of 2).
Sweden is used as an example due to their climate and take take up of the technology many years before the UK.

What is a buffer vessel?
A buffer vessel provides hydraulic separation between the heat pump and the heating circuit, improving system stability and flow management.
The additional buffer volume ensures a reliable reserve of water is available when the heat pump enters defrost mode, maintaining consistent heating performance.

We're here to help.
To give you an idea of what your property could have installed, based on its size.
However every property is unique so this is just a guide.
You may also need as many panels as your roof can comfortable fit, if you are heavy energy users.
On average a panel is 2m x 1m and you need to leave 0.5 - 1m around the edges.
South facing roofs are perfect but systems work very well on an East and West facing roof.
All our systems are designed based on your current consumption, roof orientation, obstacles and shading.
​
There are two elements to your solar pv installation with an optional third element.
-
The inverter
-
The panels
-

SOLAR PV
To give you an idea of what your property could have installed, based on its size.
However every property is unique so this is just a guide.
Due to the lower flow temperatures produced you may need to upgrade some radiators and pipework too.
We carry out a full property heat lose calculation to ensure your system is sized correctly for the property and its unique features.
​
There are four elements to your heat pump installation
-
The outdoor unit
-
The indoor unit / cylinder
-
The buffer vessel
-
The heating system
Heat pumps require a cylinder, which is sometimes incorporated into what is called an indoor unit.
Cylinders are sized based on the number of people that could occupy the property and this is multiplied by 45 litres, to give us your cylinder size.
