01 ServicesWhat each one needs
Each entry gives what the system does, what the building has to provide for it, and what is established on site.
Three systems, one contractor
Heat-pump systems
- Function
- Moves heat instead of burning fuel, for heating, cooling and hot water
- Site needs
- A position for the unit, an electrical supply and a way to distribute heat
- Surveyed
- Heat demand of the building and what the existing emitters can carry
Photovoltaic systems
- Function
- Converts daylight into electricity for use in the building
- Site needs
- Unshaded roof or ground area, a position for the inverter, a connection point
- Surveyed
- Orientation, shading over the day and the capacity of the connection
02 ApproachThree things that decide
Technical work starts with the property, not with a preselected package
Building fabric
Insulation, glazing and how airtight a building is set its heat demand. That figure, not the floor area, is what a heat pump has to be sized against.
What is already installed
Pipe sizing, emitters, the consumer unit and the incoming supply decide whether a system is replaced, extended or left in place. Those are four different jobs on the same property.
The electrical connection
A heat pump and a photovoltaic array both land on the electrical supply, and on what the connection permits where the grid is involved. It is the constraint that most often changes a plan.
03 ProcessSurvey before specification
Only the second step needs access to the property.
A clear route from enquiry to installation
- 01
Describe the property
Location, what is installed now, and what the new system has to do. Photographs of the existing plant, the emitters and the meter or consumer unit answer most of the first questions.
- 02
Define the scope
A site visit establishes what the rows above list as surveyed. What is in the job, and what is not, follows from what it finds.
- 03
Arrange the work
Once the scope is clear, the installation can be planned around the site and the agreed project.
04 CompanyOne legal representative
A Ruse-based company for building systems
A single-member company working in the city and the surrounding area, for households and businesses alike. The registration details opposite can be checked against the Bulgarian Commercial Register.

05 QuestionsRadiators, roofs, sequencing
Common questions
Will a heat pump work with the radiators already in the house?
Not always as they stand. A heat pump runs at a lower flow temperature than a gas or solid-fuel boiler, so the same radiator gives out less heat than it did before. Whether the existing emitters are enough depends on the heat demand of each room, which is why that is established before a system is specified rather than after.
Does a photovoltaic array need a south-facing roof?
South is the best case, but east and west generate too. The difference shows in the shape of the day rather than in whether the array works: an east and west split spreads output across morning and afternoon instead of concentrating it around midday. Shading across the day usually matters more than orientation does.
Is there any advantage to doing more than one system at once?
Mostly in sequencing. Heating and hot water are part of the plumbing, so those two are one job more often than not, and where an array goes in as well the electrical work happens once rather than twice. It changes the order of the work, not the specification: each system is still sized on its own.
