Replace coil size field with cylinder make and model?

[glynhudson]

Users are more likely to know the make and model of the cylinder rather than the coil size. The configuration of the coil is just as important as the size, therefore knowing the make and model of cylinder gives more insight. e.g It would be interesting to be able to compare all the systems with the HG cylinder or the new HG mini store.

Currently, about 70% of systems have the size of coil field set to 0m3.

I've just spoken to an installer who's installing a Heat Geek mini store cylinder, he's keen to put the data on heatpumpmontor. It would be very useful to have a field to record the make and model of the cylinder on the site.
