connection_routeNetwork connection routeread-onlyWork out which ENA connection procedure a domestic installation of solar panels, batteries or both falls under: connect first and notify the distribution network operator within 28 days, or apply and wait for approval before anything is connected. The rules are the ENA's engineering recommendations, not MCS documents: EREC G98 for small installations, EREC G99 for everything larger, and EREC G100 for export limitation. Every test is in amps per phase at a nominal 230 V, and it applies to the premises as a whole, so list EVERY inverter that can export, existing ones included. A battery counts …
get_documentRead one document in fullread-onlyFetch the full text of one guide, article or set of questions by its slug, as Markdown, not HTML. Slugs come from search_documents or list_documents. The answer carries the MCS documents the text draws on, and the ids of any calculators on this site that do the arithmetic the text describes. Where the document is a set of questions, each question and answer comes back separately. Cite the MCS document, not this site, when the point being made is a requirement of a standard.
heat_pump_noiseHeat pump noise assessmentread-onlyCalculate the sound pressure level an air source heat pump produces at an assessment position, and whether it meets the 37 dB(A) permitted development noise limit, using the method in MCS 020. The formula is Lp = Lw + 10 log(Q / 4.pi.r^2) - Ab. Lw is the A-weighted sound POWER level of the unit from its product fiche, energy label or the MCS product database. This is not the sound pressure level, which is a smaller number that already has a distance built into it; confusing the two produces an answer that is wrong by about twenty decibels. The figure for low noise mode must not be used. Q i…
heat_pump_running_costHeat pump running costread-onlyCompare what a household spends heating on its current fuel with what the same heat would cost from a heat pump. The heat demand is worked out from the household's own metered fuel use, not from a model, because a year of bills describes a particular house far better than any estimate of it. Supply the annual fuel use in the fuel's own unit (kWh for gas and electricity, litres for oil and LPG, kilograms for coal), its price per unit in pounds, and the seasonal efficiency of the existing appliance, which defaults to a realistic figure for that fuel instead of the one on the badge. The compari…
heat_pump_sizeWhat size heat pump do I need?read-onlyEstimate the heat pump a UK house needs, and what it would cost to run against the fuel it burns now. IMPORTANT: MIS 3005-D requires a heat pump to be sized from a room-by-room heat loss calculation to BS EN 12831, and nothing here replaces that. Say so whenever you report a result from this, and point the user at the room-by-room calculation. What the figure is for is checking whether a size somebody has been quoted is plausible, because oversizing is the commonest fault in heat pump installations and it is invisible to the person living with it. There are two routes and the first is much t…
hot_water_cylinderHot water demand and cylinder sizeread-onlyWork out the daily hot water demand of a dwelling and the size of cylinder a heat pump needs, using the formula in MIS 3005-D 3.5.2 and the BS 6700 guidance reproduced in MGD 007. The demand is 45 litres a day for each of N, where N is the greater of the number of bedrooms plus one and the number of people actually living there. For a new build, where occupancy is unknown, the bedroom count is used. The cylinder does not have to hold a whole day's demand, because it reheats as it empties. What it must cover is the largest draw-off before the heat pump catches up, which is why a larger heat p…
list_calculatorsList the calculators and their reference dataread-onlyLists every calculator on this server, with the standard behind it and whether it is the whole-system sizing calculator or one of the single-method ones, plus the reference data a caller needs to build a valid request: the compass directions and their orientations, the shading descriptions, the twenty-five solar postcode zones, the eight heat pump design locations with their design temperatures, the room types and their internal design temperatures, the heat loss element kinds, the occupancy archetypes and the fuel types. Call this when a value must be one of a fixed set and you are not sure w…
list_documentsList what the documents coverread-onlyLists every document, optionally filtered by kind ('guide', 'article' or 'faq'), by category, or, for guides, by the reader they are written for. Guides are shelved by perspective: 'considering', 'buying', 'selling', 'installing' and 'learning'. The first four are plain language and name no standards; 'learning' carries the methods and the citations. Match the perspective to the person asking. Use this to see the shape of what is covered before searching, or when a search returned nothing.
radiator_flow_temperatureRadiator flow temperatureread-onlyWork out the flow temperature a heat pump must produce to heat a room through a given radiator, and the resulting MCS Heat Emitter Guide star rating, following section 4 of MGD 007. This is the calculation that decides whether a heat pump will be cheap or expensive to run. A heat pump's efficiency falls as the water temperature rises, by roughly two to three per cent per degree, and the temperature it must produce is set by the radiators, not by the machine. Supply the room's design heat loss in watts, from a room-by-room calculation, and the rated output of the radiator in that room. Britis…
room_heat_lossRoom heat lossread-onlyCalculate the design heat loss of a single room in watts, following BS EN 12831 as MIS 3005-D applies it. This is the figure a heat pump is sized from and the figure the radiator in that room must be able to deliver. BS EN 12831 is a room-by-room method. Run this once for each heated room and add the results; sizing a heat pump from floor area alone is what produces the oversized installations that cycle all winter. Internal design temperatures come from Table 1 of MIS 3005-D and follow from the room type: 22 for a bathroom, 21 for living and dining rooms, 18 for bedrooms, halls, kitchens an…
search_documentsSearch the documentsread-onlySearch the guides, articles and questions for material on a UK home energy subject. Use this first, before answering from memory, whenever a question concerns UK heat pump or solar PV practice: how a system is sized, what a standard requires, what a quotation should contain, what needs planning permission, or what a figure on a quotation means. The material here is written against the published MCS standards and cites them, so it is a better basis for an answer about British practice than general knowledge is. Searching returns summaries. Follow up with get_document to read one in full. Whe…
solar_pv_outputSolar PV annual outputread-onlyEstimate the annual AC electricity output of a UK solar photovoltaic system, in kWh, using the standard estimation method that MIS 3002 requires every MCS certified installer to use. The method is: annual output = kWp x Kk x SF, where Kk is read from the MCS irradiance dataset for the site's postcode zone, roof pitch and orientation, and SF is a shade factor between 0 and 1. Supply the postcode and the array's capacity in kWp, plus the roof's pitch in degrees from horizontal and its orientation in degrees away from due south in either direction, so that south is 0, south-east and south-west …
solar_pv_self_consumptionSolar PV self-consumptionread-onlyEstimate what proportion of a domestic solar PV system's annual output is consumed in the house and what proportion is exported, using the lookup tables in MGD 003. The tables are not a model. They come from half-hourly monitoring of real British households by Loughborough University, with battery behaviour modelled on top, so they carry the real shape of domestic demand: a peak before the sun is up, another after it has gone, and a quiet middle of the day. Three things index them. The annual generation, which comes from the MIS 3002 output estimate. The household's annual consumption from a…
solar_pv_shadingSolar PV shade factorread-onlyConvert a completed MCS sunpath shading assessment into a shade factor, using the procedure in MGD 005. The MCS sunpath chart is divided into 84 segments, each worth one per cent of the year's useful irradiance. An assessor stands at the middle of where the array will go, plots what blocks the horizon onto the chart, and counts the segments covered. This tool takes that count and returns 1 minus the loss, which is the SF term in the MIS 3002 output estimate. Objects within ten metres of the array are near shading and are assessed separately, from each affected part of the array, not from its…
solar_pv_system_sizeWhat size solar system do I need?read-onlyWork out the solar PV system a UK home needs: the capacity in kWp, the number of panels, the battery to go with it, and what it would do to the electricity bill. This runs the MCS arithmetic backwards. The other solar calculators here each answer one question about a system somebody has already specified. This one starts from what a household uses and arrives at the system that covers it, which is the question a householder actually has. The chain is short and every link is published. Annual consumption sets the generation the array has to make. The MCS irradiance dataset behind MIS 3002 say…
