Less efficient, but far less disruptive to install, are decentralised systems. Lower recovery of heat (70-85% vs centralised 90+%) but much more simple installation.

In essence, they remove warm, wet air from your house, pass this through a heat exchanger and supply air from outside, warmed and dry, in.

Work best in well insulated, well sealed properties. Sealing is more important than insulation for good MVHR function.

Centralised installation disruptive...

If you fancy a bit of investment in your home: MVHR.

We installed a centralised system* around a year ago. Humidity levels dropped from 60-90% (yes really!) to 45-60%.

Alternative was a second car (or a motorcycle/side car!). We'd have spent more in insurance alone on a second car in the 2 years we have had the RW than we spent on buying, kitting-out and running the RW.
Lost count of the number of admiring comments. Once you've made the shift, can't go back.

We bought a Radwagon 4, second hand, for about £1k (inc accessories to enable 2 kids). Since then, we've spent a bit more on more kit (e.g. XL panniers) and now it covers around 50km per week (including almost all moving of kids and shopping).
If we hadn't bought 2nd hand, we'd have used C2W.

Gloves. Snood, up over ears. Decent socks. Cover extremities, it makes such a difference.

This is on the A38 between Toyota Island and Little over near Derby. It's the silliest locally that I know of; close second is a lamppost in the centre of a cycle lane.

This is my favourite Cyclists Dismount sign. Present on both sides. Bonus points for give way markings (not sure who is giving way to who).

Combine PPM with elements of VED, and bring in weight classes. Fuel duty to remain. It could encourage people out of polluting vehicles, but also out of e-SUVs.

Just introduce PPM for all vehicles that require a licence - motorbike, car, van, LGV, HGV etc. Combined with elements of VED, it could be a sliding scale based on emissions and weight. Combined with fuel duty, this would encourage both lighter and lower emissions.

From the comments:

"Bicycles are a fairweather mode of daytime transport used exclusively by able bodied middle class men"

I better let my wife and kids know they need to stop cycling, and I now know I shouldn't have done a £50 shop on the bike in the rain yesterday evening. Silly us.
