Heat Pumps: anyone have one/thought about it?

There is no price it's meant to be free.
Happy days, is this is the scheme for those who are on low incomes?
Either way post up the proposal of works, it’s always worth a sense check.
The main thing with a heat pump is to get the heat loss survey correct and setting up the controls properly once installed.
You can check their heat loss calculations using the heat punk website.

Low incomes and certain medical issues.

In the process of having an install in my renovation project. Floor (suspended timber), has been lifted and insulated. We have gone for radiators on a manifold system and a 5kw heat pump with unvented cylinder. Will drop some more details shortly.

Depends on the situation. If you have microbore then higher temperature is better. If you want a bath, higher temperature is better.
The cost of heat-pumps is very high. They are not as efficient as they are cracked up to be and they are more expensive to maintain and later replace. It's not to say they aren't any good, but they don't suit everyone.
It's true, if you don't have a central heating system then it doesn't need retrofitting for a heat-pump and if you don't have any insulation then you need some anyway! As I say, every case is different.
Of course you have to have somewhere decent to put a heat-pump too.
You can run your heating and hot water at different temperatures, 50C is more than fine for hot water and is more than achievable on a regular heat pump, you'll still be mixing down at 50C as its too hot bath/shower in. The only advantage of hotter hot water is you can store more energy in the same size cylinder, you'll be paying for it still.
Microbore might be an issue, it might not even with 8mm microbore. It depends on your heat loss and how much flow you need to get around the pipes. I've got 10mm microbore, its not an issue.
The units are more expensive to buy but they cost less to run and should last a long time, it should come out in the wash. Servicing is so, so and largely because there is little competition in the market, not that there is really anything to 'service' outside of cleaning the condenser - feels like a bit of a warranty racket to me. Once the warranty has expired, I'll not bother.
Efficiency is a function of your target flow temperature, how well your controls are set up and if the installer did the heat loss calculation properly. The issue is that difference between a bad gas install and a good one is 10-30% efficiency loss most people don't notice or care, a heat pump it could be 10-200% loss, it can go very wrong.
Heat pump placement can be problematic but the rules are being changed in a few weeks to be less problematic. We only really had 2 places ours could go, one of which was vetoed by Mrs Sk8. Neither were perfect and as its a retrofit, it means there is an external pipework run but it is hidden by the geometry of the house most of the time.

I did an online quote with e-on last night, they saying 10.5k - 7.5k grant = 3k…..
My boiler will need replacing this winter, so seriously thinking about it on those grounds.

Our heatpump is an older model and its not silent by any means - but its cerainly quieter than my parents oil boilder that sounds like a trainee digeridoo player thanks to the vertical extension on the flue

What change is coming? I'd be keen to find out what planning regs might change, I'm looking at options too
Basically to get shot of some of the placement constraints.
Permitted development changes aim to boost housing potential
The UK Government has opened a consultation which proposes amendments to permitted development rights that remove barriers to the installation of air-source heat pumps and charging points for electric vehicles. Changes to the rules on altering and extending properties are also put forward to...

To be fair to ours, it would be that way too if it wasn't between our house and our neighbours house - the facing brick walls seem to pick up the exact frequency of the compressor at low load and throw it into our hallway window - its still not what I would call loud.

This is going to be a game-changer for people who don't have an airing cupboard, or they have one but it's too small, like what I was told from Octopus.

They have basically inverted the cylinder. The hot water from the heat pump (or boiler) flows into the main body, not the coils.
And hot water on demand flows through the coils and is heated as used, just like a combi-boiler. No expansion vessel is needed, no legionnaires cycle needed as there is minimal water stored, and it's always flushed through the coils.
It will fit inside a standard kitchen cupboard under the worktop. There are a range of sizes available if you have a bit more space.

How is that any different to a thermal store?
Probably coil density due to the lower cylinder temp

Here's what Heat Geek say;
"I don’t think thermal store is a good description for the ministore… . People are calling it a thermal store just because the DHW goes through the coil. A normal hot water cylinder is also a thermal store officially.. you heat it and store it until use.The ministore is more like a tube in tube heat exchanger. As it gets most of its energy from the heat pump recharging it rather than its stored reserves (like a combi with preheat switched on).If you have to categorise it I would say a tube in tube heat exchanger with built in buffer. Or a heat pump powered instantaneous water heater. But not a thermal store.Traditionally a thermal store is used to describe something that keeps the whole heating system (including rads) at hot water temperatures, so way less efficient for heat pumps."
Sounds like a small thermal store to me. The small size being the limiting factor which they are selling as a plus point.

So with that. You don't need a hot water tank? People with combi boilers can just do a swap?This is going to be a game-changer for people who don't have an airing cupboard, or they have one but it's too small, like what I was told from Octopus.
