Comparison
Verdict in brief
The MagnaTherm MGH 1600 and MGH 2000 share one cabinet: 320-1,600 versus 400-1,999 MBH input and 1,520 versus 1,895 MBH maximum output, both at 95% boiler thermal efficiency with 5:1 turndown and 22 gallons of water content. The 2000 adds 375 MBH of output at the same shipping weight.

| Specification | Laars MagnaTherm MGH 1600 | Laars MagnaTherm MGH 2000 |
|---|---|---|
| Input, minimum | 320 MBH | 400 MBH |
| Input, maximum | 1,600 MBH | 1,999 MBH |
| Output, minimum | 304 MBH | 379 MBH |
| Output, maximum | 1,520 MBH | 1,895 MBH |
| Efficiency (thermal) | 95 % | 95 % |
| Efficiency (combustion) | 96 % | 93.6 % |
| Water content | 22 gal | 22 gal |
| Shipping weight | 1,590 lb | 1,590 lb |
| Turndown | 5:1 | 5:1 |
The Document 1429 submittal lists the MGH 1600 at 320-1,600 MBH input, 304-1,520 MBH output and 95% boiler thermal efficiency; the MGH 2000 lists 400-1,999 MBH input, 379-1,895 MBH output and 95%.
Both share a 1,590 lb shipping weight and 22 gallons of water content, so the 2000 fits the same footprint and rigging plan while delivering more capacity.
Combustion efficiency differs in the printed table — 96.0% on the 1600 and 93.6% on the 2000 — and both run the Laars Linc control with Vari-Prime pump control.

Yes — the Document 1429 submittal prints the same 1,590 lb shipping weight and 22 gallons of water content for both sizes.
The base MagnaTherm modulates down to 20% of full fire for a 5:1 turndown; the MagnaTherm HTD is the 20:1 version of the same platform.
A consultation includes a heat-loss review so the size is right the first time.
