Full Central Heating Installation Cardiff

Project details:

Installation of a full central heating system including radiators, pipework, and an Ariston Clas ONE Gas Combi Boiler into a property development in Cyncoed, Cardiff.

Customer Requirements

In April 2021, we were approached by the owner of a property development on Cyncoed Road in Cyncoed, Cardiff. They were looking for a full central heating system installation including radiators, pipework and a new boiler. 

The property this was to be installed in, is a detached bungalow, that had been a doctors surgery for many years and had been granted planning permission to be redeveloped into a day nursery. As part of the development of this property, the owner was looking to upgrade the heating system in preparation for becoming their new business premises. 

The nine-room existing property development consisted of multiple rooms including five rooms which were formerly consulting rooms, two WCs, a waiting room, and a lobby/ reception area. These rooms were to be redeveloped to fit the needs of a modern-day nursery and required a heating system to suit this.

Our Solution

Upon contacting Boilerhut, we evaluated the customer’s requirements and advised that the property would need its gas pipework upgrading. The property’s existing gas supply pipe was 15mm. However, in order to meet Gas Safe regulations, this needed to be replaced and upgraded to a 22mm supply pipe from the boiler to the meter.

Along with the full gas supply pipework upgrade, we recommended the installation of 13 radiators and a 38 kW combi boiler. After discussion with the customer, it was agreed that they would like the installation of an Ariston Clas ONE combi boiler and our installation would comprise the following items:

  • 1 x Ariston Clas ONE 38 kW combi boiler
  • 1 x Ariston horizontal flue
  • 1 x Spirotech SpiroTrap magnetic filter
  • 1 x Ariston Cube S Net WiFi boiler thermostat
  • 22mm gas supply upgrade
  • Lagging of all new pipework in the attic
  • 13 x high-efficiency radiators
  • 12 x 15mm thermostatic radiator valves
  • A chemical flush and addition of an approved inhibitor to the system

Installation Details

The full central heating system install and fitting of the Ariston Clas ONE combi boiler took place over multiple days. In order to undertake the installation we were required to work alongside other tradesmen including builders and joiners who were also working on the development of the property. 

Our installation involved the laying of the pipework in each room of the property and the positioning of the radiators. From here, we then undertook the installation, connection and lagging of the new pipework in the attic. Finally, we hung the radiators, installed and commissioned the boiler and undertook a chemical flush of the system.

Our Recommendations

As mentioned above, we advised the customer that they would need to upgrade their pipework in order to meet Gas Safe regulations. 

In regard to the boiler, we recommended the Ariston Clas ONE due to it being a highly efficient boiler that would save the customer money on the energy bills. Due to needing to provide the heat for 13 radiators and needing to provide high levels of hot water, we recommended that the 38 kW combi version of the Clas ONE would be most suitable for the property and its requirements as a day nursery.

One of our main reasons for recommending the Ariston Clas ONE, is the stainless steel heat exchanger that it is equipped with. Designed to retain efficiency for the lifetime of the appliance, this is a major selling point of this boiler and ensures that there would be no sudden spikes in the cost of the customer’s monthly gas bill that are related to the boiler’s efficiency. This combined with the comprehensive 8-year warranty, gives the customer peace of mind that they have many years of trouble-free heating ahead of them. 

Upon our suggestion, the customer opted for Ariston’s Cube S Net WiFi boiler thermostat. Bringing additional technology to the heating system and OpenTherm compatibility, this plug and play device allows for remote monitoring and adjustment of the heating system, plus it brings modulating technology, weather compensation, and programming functionality to the boiler system.

We also recommended the installation of 12 thermostatic radiator valves, these will enable the customer to control the temperature of each radiator room by room, something that will be especially useful for a day nursery catering to the needs of different age groups.
