Full heat loss on my property. So this is a full system design, flow rates, velocities, pump sizes, all that stuff. I've got Jordan here from H2X and yeah let's get into this video. http://www.h2xengineering.com/

Heat pump's gone and we're getting a brand new extension. So the heat loss calculation that we did previously is no longer relevant. What we're going to do today, we're going to do a full heat loss system design, flow rates, velocities and all that stuff. We're going to measure windows, we're going to measure rooms, we're going to measure radiators. We're going to look at the thermaskirt as well, how that will work with the new system we're going to put in. Also in this area we're going to put underfloor heating in here. So again we're going to show how that will work of it as well. So yeah let's go inside and let's do a full heat loss. All right so you're having an extension downstairs so we've got a plan for downstairs and then upstairs we're going to create the plan from scratch in H2X. Start off you can upload PDF floor plan.



With the settings you can open up your project settings. You can put in the address here. Once you've looked up the address it's going to tell you the external winter sort of design temperature. From there you can do things like set your ground temperature. You can allow a percentage with the whole bridging through the materials and you can set a spare capacity as well. So if you wanted to be a bit conservative with your heat loss you can have like 5% 10% but people use that for intermittent heating, exposed locations or reheat times. The external walls, did you say like they mainly they've mainly got internal wall insulation? Yeah so downstairs they've all got internal wall insulation. And then upstairs most of them as well yeah. Brick with IWI. We can set that to be that external wall and that we can use U-value no point for E for that. Once that's done yeah this is where you just start to draw out the room. So pick your room like this and you just go around the internal walls.



Like so and yeah based on your settings it's just going to start doing your heat loss as you go.



Because it's doing it on like the clicker miles it does make it like very easy. If you've got plans because you can just do like any sort of shape of room. Based on your all your values that you've set like your room heights and stuff like that it's working out. Your air change is based on the age of the building and the heat loss is shown in the middle of each room and then it's also sort of adding it up at the bottom down here as we go. This part's the new extension now. So I'm guessing this is all going to be to building regs. Because this part is like different material to the rest like we can click on these walls now. And we can change the U-value so because this is new rather than having like your brick with IWI we can say this is going to be building regs so of a slightly lower U-value. From that I just go around and start popping windows on so you can every time you've got a window just draw it on like that and enter the height. So is this the total heat loss for the house for downstairs now? This is just the downstairs yeah so it's you still gotta put window heights in. What's this suitable for and what size properties?



Anything really like anything from like see getting used on two-bed terrace like all the way up to like luxury residential commercial. I'd say it really comes into its own and on like a property like this where you've got like a large space. Awkward. Yeah well it's doing this in any other way will be even more challenging I would say without the software like when you've got awkward room types and stuff like that when you're clicking around with the mouse it's not really any extra effort to like do an awkward room type or anything in this whereas like it can be if you're trying to do it in like an excel spreadsheet or something like that. And what about like vaulted ceilings and different slopes and stuff like can it work with that stuff as well? It can yeah. If we had a level above here you can set like your finished height so we can put that to
