Bath Preservation Trust and the Centre for Sustainable Energy PRESSING FOR CHANGE Local views on heating systems in listed buildings in Bath The following results describe the extent to which Bath residents who responded to our online survey agreed with the given policy options for listed buildings. These results do not describe current Council policy. 56 Boiler flues Seventy percent of Bath respondents supported the installation of boiler flues on the secondary facades of listed buildings in the city, regardless of visual impact. Nearly half also supported their use on primary facades where there is no practical route to a secondary facade. 10% The installation of boiler flues should be permitted on all facades of all listed buildings in Bath. 36% The installation of boiler flues should be permitted on secondary facades of all listed buildings in Bath. Flues should only be permitted on primary facades where there is no practical route to the rear facade. 24% The installation of boiler flues should be permitted on secondary facades of all listed buildings in Bath. 28% The installation of boiler flues should be permitted on secondary facades of any listed building in Bath where this does not have a significant visual impact 1% None of the above. Among respondents who live in listed buildings in Bath, 74% supported the installation of boiler flues on the secondary facades of listed buildings in the city, regardless of visual impact. Nearly half (49%) supported their use on primary facades where there is no practical route to a secondary facade, including 9% who support their use on all primary facades. Bath Preservation Trust position The Trust supports the installation of boiler flues on the secondary facades of all listed buildings in Bath. Outlets should be discreet and painted to match the colour of the external wall. Wood burners and boilers Almost all Bath respondents supported the use of wood burners and boilers in the city’s listed buildings, though for two thirds this is only acceptable as long as an existing flue can be reused without damage to a significant grate. 30%: The installation of wood burners and boilers should be permitted in all listed buildings in Bath. 66%: The installation of wood burners and boilers should be permitted in any listed building in Bath where an existing flue can be reused without damage to a significant grate. 3% The installation of wood burners and boilers should not be permitted in any listed building in Bath. 1% None of the above. Among respondents who live in listed buildings in Bath, 96% said they should be permitted in listed buildings, including 66% who wanted this only where an existing flue can be reused without damage to a significant grate. Bath Preservation Trust position The Trust supports the installation of wood burners and boilers in listed buildings in Bath as long as an existing flue can be reused without damage to an original grate. Air source heat pumps Three quarters of Bath respondents support the installation of air source heat pumps on secondary facades of listed buildings in the city, as long as they do not have a significant visual or noise impact. 13% The installation of air source heat pumps with intakes on secondary facades should be permitted in all listed buildings in Bath. 61% The installation of air source heat pumps with intakes on secondary facades should be permitted in any listed building in Bath where they are not visible and do not have a significant noise impact. 22% The installation of air source heat pumps should not be permitted in listed buildings in Bath. 3% None of the above. Among residents who live in listed buildings, 72% support the installation of air source heat pumps on secondary facades of listed buildings in the city, as long as they are not visible and do not have a significant noise impact. Bath Preservation Trust position The Trust supports the installation of air source heat pumps with intakes and/or outlets on secondary facades as long as they do not have a significant visual or noise impact.
Improving the energy efficiency of traditional homes in the City of Bath Solar energy Most of the historic city of Bath faces south. The bowl cradles the city in such a way that the rising terraces enjoy abundant sunshine throughout the year. The builders of Georgian Bath were well aware of the value of sunshine in bringing heat, light and delight to their new homes. Unlike many modern homes, built with modest windows (for walls are cheaper to build than windows), most of the traditional homes of Bath celebrate the light. The builders of Bath would perhaps have been more sympathetic to solar panels than many of today’s builders. A beautifully detailed, wrought-iron Victorian solar panel would have been a joy to behold. Although the technology is modern, many of the traditional buildings of Bath are particularly well-suited to solar panels. The Georgian valley roof is ideal as it offers a safe environment to install and maintain solar panels, substantial unshaded roof area, and protection from the gaze of those who wish to admire the buildings of Bath without modern accretions. However, as the majority of roofs in Bath are not protected in this way, the potential impact of solar panels on the look of the city cannot be ignored. One way of reducing the visual impact of solar panels is to integrate them into the roof finish itself. This can be achieved with Heritage solar slates which are designed specifically for traditional buildings as a replacement for traditional slates. They remain, however, an expensive option and the rather shiny solar slates still look different to a slate roof. Before you consider whether or not a solar panel will look right on your roof, ask yourself whether this is the most appropriate action to be taking. It makes little sense to start producing your own energy if you are currently throwing energy away on a regular basis. Measures to save energy and use energy more efficiently should A solar thermal panel, discreetly placed on the rear roof a Victorian house in Bath. This panel uses evacuated tubes to improve the efficiency of the solar collector. 57
