For Occupiers

We always encourage occupiers to choose the largest Power-Pipe that will fit into the available space. The larger the unit, the greater the efficiency performance and the more energy (and money) will be saved in the long-term.

For Developers

When it comes to developers, they will be influenced by slightly different factors. They may opt for the most cost-effective solution to pass their SAP calculation, so are more likely to choose a smaller unit which will provide enough of a carbon saving to meet required targets.

However, because of the cost-effectiveness of WWHR compared to other products in the SAP calculation, we would still advise they apply the same logic and install the largest Power-Pipe they can. Instead they should look at making savings elsewhere by relaxing the fabric u-Values of the property which are comparatively more expensive than WWHR.
