Stove Boiler outputs and Chimney Design

[Mostie]

Hi, after reading Simons first question, can you... using the 4 connections, gravity feed one set to a large rad, and the other to the DHW tank?

Yes it seems some use their wood burner boiler connections this way.     If the radiator circuit is bigger, thermostatically controlled one,  and  has a pump on the return to the boiler it should still allow gravity flow to the cylinder.  The drawback would be a lot of pipes around the stove.

thanks.

Hi after another spell recently on the forum I am slowly but surely moving forward / improving my knowledge. To allow me to go away again and ponder on the advice given could you advise on the following.
I plan to get a Load Unit and would like to know if anyone finds the noise a problem in the front room or knows a quieter model), also on the topic of load units - If I can place unit behind to the side of stove within the fireplace it will make pipe runs simple. Does it matter how close it is to stove - I assume on the diagonal stove tappings A and C you would connect the shorter pipe run to stove on the return and the longer pipe run on the flow. If I do this it means the cold pipe to unit would be approx 6-8 inches long and hot  15 -17 inches long.
And Brandon earlier you had mentioned a 1000L store tank (because I am to have a Well installed)  - Is this a rigid plastic tank and with a single pump that  would connect to the DHW coil in store or perhap a PHE.Would this be better placed inside and how much approx can they cost.
My current  setup/plan/ budget is Stove/300L Thermal Store/Load Unit/ Solar I like the idea of a larger 1000L plus store when I can afford a gasification boiler to run rads, is there any future proof tips to bear in mind at this stage to allow such an addition at a latter date and finally I had planned to keep rad circuit independent of store but now I plan to link flow and return to the small thermal store and possibly add PHE, Question -  are pumped circuits bad economy on small stores bearing in mind the Newark cylinder ( I will not be retrofitting any diffusers - Install out the box) Thanks

simon,

the real beauty of the thermal store is the ability to use as many heat sources as you can, provided that you allow enough tappings at the design stage (that is an aspect of future proofing).

I do not have the details of the 1000 liter tank, but a black IBC would probably do. that could be pumped in conjunction with an expansion vessel and pressure switch, to the cold taps, and straight through the coil in the store, and to the hot taps.

Hi Brandon, thanks for responding - To make sure I have understood would the pump setup be: The control pump would be fitted between the storage tank and thermal store and expansion vessel fitted between pump and storage tank , the expansion vessel reducing the amount of times the pump needs to activate ?.

Any links to pump suppliers or model / name would be appreciated to assist in  my finanacial planning etc

Cheers Si

we have had good success with DAB pump/expansion combos (think compressor layout)
