Heat Pump vs Oil Boiler. It's a no brainer.

today we are installing an air source heat pump in this little Bungalow behind me it's been running on oil for the last 25 years cuz this area has no Mains gas and in this video you're going to see what's involved in converting an oil system into an air source system what we have outside is an big tank for oil because there is also an external oil boiler they've run the pipe work underground in plastic push feet you see this is a comb Bo boiler so you've got four pipes going in and out hot and cold flow and uh return we are in the kitchen and the oil boiler is just behind the window and the way they've run the PIP work there's plastic pipe work going below the kitchen units then it goes to copper right here splits to heating on the ground floor and then goes through the Loft to the old airing cupboard in the middle of the property so kitchen is just right here and the bathroom on the other side of this wall and the hallway behind me so there are no external walls in this aing cupboard and they've swapped the cylinder for a radiator so they could dry their towels you know that's what people used to do when vented cylinders were taken out so we're putting an unvented cylinder here and the problem we have or difficulty a difficulty is getting tempure and pressure relief to the outside the way I'm going to try to do it is by going through this wall and that wall goes to the kitchen and it will come under those kitchen units to the outside so that's going to be probably relatively tricky shouldn't be impossible though Cabo finished plant room I don't think it takes too much space probably the same what it used to be with the old cylinder before they went oil outside and the oil Combi boiler there used to be a cylinder here vented cylinder we have changed it now to unvented and we went with temperature pressure relief it's a safety pipe it always needs to go to to the outside so sometimes it's a consideration when cylinders are installed in the middle of the property luckily we managed to get the pipe under the kitchen cabinets to the outside let me talk you through the PIP work while it's still not locked uh so you can understand how this is system is piped coming from here this is our mze going to the cylinder here on the bottom means water then here second pipe is hot water going back to the house obviously going through main Supply goes through the expansion vessel after the combination valve so this is a pressure reducing valve and also has an expansion valve if there's too much pressure that will will go here and to the tan dish and to the outside this pipe here the first 28 mil pipes we've got 222s M water hot water this one here is the main flow coming from the heat pump outside through the Loft and that flow goes to a diverter valve on one side goes to the cylinder on the other side goes to our heating system to the radiators now the second pipe this one here that connects to the expansion vessel that's a primary return this is return going back to the heat pump now expansion vessel should Al always be on the return pip work or the suction side of the circulating pump F and Flash valve we're going to use it in a second to clean the system we haven't done it yet then we've got our heat meter and then we've got this last T here that's a t from the heating system and that's a y strainer from the heating system so we we can isolate it with those valves here and clean it on the services there is a little mesh inside and obviously the other return is coming back straight from from the cylinder and that would be all for the pipe work on the control sides heat pump interface unit uh this is really not for the end user receiver for the controls internet gateway power supply for the internet gateway and power supply for the monitoring so if you install monitoring or internet gateway you need to put two additional sockets spare switch for the uh here for the controls right right here for a heat pump interface unit and a backup immersion heater right here this is obviously a bangalow and Bungalows are pretty nice for running pip work in the Lofts cuz usually Lofts cover the whole floor space and you've got access to every single room and the worst you might have to do is to chase pip work or drop the PIP work on the wall for radiators and here in the Loft we've run both our primary pipor flow and return going from the heat pump from here uh over there and we've also run then pip workk for central heating back to the radiators and we've done it all in a 32 mm mlcp and then we've run 28 mil copper in the plant room as well just how gigantic is this tank and this boiler this boiler is probably even bigger than the heat pump Wis installed here and much more polluting much more noisy and I mean this bit of Kit my God you're on petrol station in the garden who would want that so this unit behind me is now running at almost maximum power doing hot water for the first time and you almost have to look at it to know it's on it's so quiet I know people say with time they'll get noisier install them well install them level and they'll be whisper quiet for years now we can also talk about running costs cuz right now oil is about 63 65 pound per liter electricity I think new cup is 22 pound so oil is kind of competitive it's not crazy expensive however we've designed this system to run at maximum of 40° celus flow so this system will only run at 40 C when it's uh minus 2 outside that should result in a cope or seasonal coefficient of performance of over four 4.2 I think and that means this setup will be about roughly 10% cheaper to run than oil so we know it's quieter we know it's cheaper to run and also look at how problematic this oil setup must have been imagine taking deliveries of oil this pollution in this beautiful area having to smell the fumes from oil boiler it's uncomparable how much better welld designed and installed system air source heat pump system is to any oil boiler in bedrooms we've got one double panel radiator reach 1,200 by 500 in the living room we've got two uh double panel K2 radiators of the same size all of those radiators will run at maximum flow of 40° so they only get to 40° when it's around minus 2us 3 outside so all this system will run a deficiencies of well over uh 400% or for those of you who don't like uh percentage efficiencies coefficient of performance of four and over if you look into the viland book it should run at those temperatures at 4.2 but from experience I know that those systems usually run higher the ones that we install so around 4.5 4.6 on hitting and probably around three or thereabouts uh on hot water so this system is already running and I've just connected this internet box to it and that should bring my open energy monitoring online so we can see how it performs see that code here if you scan that code it takes you straight to the monitoring of the [Music] system there we go the system's running and you can have a look at it so right now it's running at the cup of 6.25 go and have a look for yourself so you can see what it's doing uh what the system is doing right now cuz anyone can access live monitoring of of those setups are those systems those open energy monitors worth installing uh cuz they they are expensive the kit is about 600 including that maybe 700 which is a lot but in my opinion those systems are worth every penny the insights you can get into them no heat pump onboard monitoring will ever allow you to do what this system allows you to do is to fine tune your setup because what you can do you can make changes to your settings on your uh heat pump programmer and see instantly how it affects performance and that way you can dial in the most optimal settings and I would argue that over the lifespan of the system of 15 to 20 years this system installing open energy monitor will pay for itself many times over just in Energy savings and also extending the life span of the system because you can instantly see if the system is cycling and address the issues so we don't have too many compressor starts I absolutely love those setups if you have open energy monitor installed on your heat pump please let us know if you think it was worth spending the money to have it installed leave a comment so we can start a discussion about open energy monitoring kits and how it helped you with your own setup and you have to agree this Garden side of the house looks so much better without that gigantic tank and an oil boiler smells gone all noise is gone more efficient cheaper to run setup has been installed and I know the landlord cuz this is a rental property is also putting battery storage and solar his tenant they will absolutely love him for that because this house will have zero bills on Heating and hot water I think that's the way forward don't you agree
