St. Johns College Waterford

Multicolumn & Radik Klasik Radiators

Mythen Construction turned the sod on 20th December 2013 on an exciting new project/development for Respond! Housing Association in partnership with the Department of Environment, Local Government and Communities. The development consists of the redevelopment of the existing St John’s College Building (a protected structure of approx. 3900sq.m) to include communal facilities and 21 apartments on the upper floors plus the construction of a new block of 36 apartments (2400sq.m) and associated works.

The College dates back to the 19th century and was a seminary up until its closure in 1999. It was bought by Respond! from the Diocese of Waterford and Lismore in 2007. It is a listed building status which Respond! has respected in its plans. ‘The whole redevelopment will provide a fitting and resourced location for some 57 older persons,’ said Fr. Cogan.

 Heating Solution

There was significant damage on the upper floors of the landmark Gothic Revivalist style building due to water ingress with outbreaks of dry rot and deterioration throughout, due to a lack of heating. The building’s former library was transformed into a multi-purpose Activation Room that will cater for Respond! tenants, Day Centre users and people from the wider community.

In this area it was decided to use Zehnder Multi Column Radiators as the client wanted an aesthetically pleasing radiator that would provide sufficient heat output to meet the necessary demand. The old dining room will become a purpose built Day Centre which will cater for older people and people with specific needs and requirements. It’s envisaged that the Day Centre will become a lively social hub for older people in this area of the city and will offer varied activities.

Located off this room is an impressive conservatory which has been fitted with specialised glass which will ensure it’s not too hot in summer and not too cold in winter. In this area, floor mounted multi colum radiators were used, again taking the aesthetically pleasing look into consideration.

The Chapel and Gallery in the College remained largely intact, possessing some of the finest stained glass windows in Ireland. However, much effort has gone into improving this stained glass and the result is certainly very impressive.


In total, there are 21 apartments within the college building which are designed in the same style and offer plenty of space and natural light. The building is fully wheelchair accessible and fitted with a wheelchair lift. The apartments which are located alongside the college overlooking The Folly also offer plenty of space and natural light and are fitted with a new Heat Pump heating system.

The Korado Radik Klasik steel panel radiator was used in the apartments and the new build, working in conjunction with the new Heat Pump heating system.
